Best pfSense and OPNsense Hardware (2026): Fanless Mini PCs

Before you buy a box for pfSense or OPNsense, settle one question. How fast is the link you are protecting, and what else should the firewall do? That answer decides almost everything else. A plain NAT gateway on a gigabit line runs happily on a four-core N150. Turn on deep packet inspection and a couple of VPN tunnels at 2.5 Gbps and you need real cores, or the throughput falls off a cliff.

This guide compares the best pfSense and OPNsense hardware for 2026: fanless mini-PC firewall boxes built on Intel’s i226-V 2.5GbE controller, which both platforms drive without driver patches. Two earlier picks sold out, and newer N150 and Core 3 N355 boards are shipping, so the shortlist changed. We updated this guide in November 2026 to add a used thin-client route. The listings, store pages and stock states below come from our 30 October 2026 pass ahead of Black Friday, and the prices are what a cart showed that day. Throughput figures come from published measurements, never from numbers we made up.

Our picks at a glance

Five boxes cover almost every home and small-office firewall we get asked about. Each one wins on a different constraint, so pick the line that matches yours and skip to its section for the trade-offs.

• Best overall, fanless and ready to run: MeLE Business-Grade Quieter DL. An N150 with two Intel I226-V ports, RAM and an SSD already fitted, and no fan to fail.
• Best budget four-port firewall: CWWK N100 four-port, or the newer CWWK F8 from CWWK’s store. Four i226-V ports in a fanless chassis for routing, VLANs and a VPN tunnel.
• Best built-for-firewall box: Protectli VP2430e. The N150 successor to the VP2420, with four I226-V ports, DDR5, a coreboot option and a vendor that answers support tickets.
• Best for IDS/IPS and many segments: Qotom Q10932G6. Eight i3-N305 cores for inline inspection and six Intel 2.5GbE ports, with CWWK’s N355 six-port F5 as the one to watch for a restock.
• Best turnkey, officially supported: Netgate 4200. pfSense Plus pre-installed, published throughput numbers and Netgate’s own support.

Our disclosure box above this article covers the affiliate links. CWWK and Netgate also sell direct, and those links go to the vendor’s own store. CWWK prices there swing by more than $100 with the CPU and memory you tick, and stock differs by build.

How we picked these boxes

Three things separate a firewall box that lasts from one that frustrates you. We weighted every pick on all three before looking at price.

• The network controller: only Intel i226-V boxes made the list, because pfSense and OPNsense drive that chip natively through the FreeBSD igc driver. Realtek 2.5GbE parts work eventually, but they’re behind most “why does my throughput tank” threads, and our NIC comparison for OPNsense and pfSense shows why.
• Honest CPU headroom: any N-series chip routes a gigabit at line rate, while inline inspection (Suricata or Zenarmor) and VPN encryption are CPU-bound. We lean on Serve The Home’s N100 platform testing, homenetworkguy’s Protectli review, rovingclimber’s i3-N305 power figures and Netgate’s own published numbers.
• Who supports it: CWWK is excellent value and thin on documentation. Protectli and Netgate cost more and answer the phone, and that difference is real money and real time.

We have not bench-tested every one of these exact units, so where a number is cited rather than measured by us, the sentence says whose it is. Our own iperf3 matrix of NAT against IDS against WireGuard on one mini PC is a separate piece. Stock mattered too this time. A box that shows “currently unavailable” on the day you are ready to buy is not a recommendation, so we dropped the two picks that went that way.

pfSense and OPNsense hardware compared

The columns below are the ones that change the decision. “Ships as” tells you whether you still need RAM and an NVMe drive. The price is what we saw on 30 October 2026 for the build named, so check the live price before you order.

Read the table by its extremes. The barebone CWWK boxes stop being cheapest once you add a DDR5 SO-DIMM and an NVMe drive. The most expensive box, the Netgate, does not have the fastest silicon. In practice you are choosing between paying in parts and assembly time, or paying a vendor to do that for you. Each pick section says which side of that line the box sits on.

The Black Friday price check

A strikethrough price on these listings is mostly decoration. We would judge a Black Friday deal against the cart prices we recorded on 30 October 2026, not against the “was” figure. CWWK’s store shows a $499.00 compare-at price on most F8 variants, from the $252.93 N100 barebone to the $1,417.88 N150 build, which says nothing about a real discount. Amazon’s only listed markdown on our picks was the CWWK N100 four-port at $355.91 against a $375.91 list price.

• MeLE Business-Grade Quieter DL: $389.99 with 8GB and 256GB fitted, no list price shown. Anything under that is a genuine cut; MeLE’s own store charged $449.99 for an 8GB/128GB build the same day.
• Protectli VP2430e: $469.00 barebones on Amazon, with a coreboot listing at the same price. Stock showed “only 14 left”, so a sale may simply sell it out.
• CWWK F8 and F5: only N150 builds up to 16GB were in stock in CWWK’s US store on 30 October 2026. Every N100, i3-N305, N300 and N355 build showed sold out, so a restock matters more than a discount here.
• Netgate 4200 MAX: $829.00 with TAC Lite and no sale price listed when we checked, so budget the full figure until one appears.

DDR5 and NVMe pricing has swung hard through 2026, and that hits barebone boxes twice: once in the configured price and again when you buy the parts yourself. If a barebone deal looks great, price the 16GB SO-DIMM and the SSD in the same session before you call it a win.

MeLE Quieter DL: best overall for most homes

Most homes with one WAN and one LAN should start here.

The Quieter DL combines what the others make you choose between: two Intel I226-V 2.5GbE ports, a fanless chassis, and RAM and storage already fitted. MeLE pitches it for pfSense and OPNsense soft-router use as well as general homelab duty. The N150 is a modest four-core chip with a 6W base power rating on Intel’s spec sheet. Routing a 1 Gbps or even a 2.5 Gbps line is light work for it, so it sits silently in a closet and barely registers on the power bill.

Buy the right listing, though. The Quieter DL comes in several builds. MeLE’s own spec table lists dual I226-V for the N150 model and a Realtek RTL8125BG for the N100 option, and an independent roundup on starryhope ties the Realtek parts to the LPDDR4x builds. Either way, we’d only buy a listing whose title names the Intel chip. The Business-Grade 8GB/256GB listing does, and it also advertises an unlocked BIOS, which helps when you want to tune C-states or ASPM later.

Who it is for: anyone whose internet is one WAN and one LAN, which is almost every home. You run the WAN into one port and the LAN into the other, then carve out guest and IoT networks as VLANs behind a managed switch. If you haven’t done that before, our router-on-a-stick walkthrough shows the pattern on Cisco gear (the trunk-and-subinterface idea is the same on a firewall), and it pairs naturally with a managed 2.5GbE switch.

Skip it if: you want physically separate ports for WAN, LAN and a DMZ without touching VLANs, or you plan to run Suricata at 2.5 Gbps. Two ports and a low-power chip are the hard limits here. The single M.2 slot also means no mirrored boot drive, which matters more to a small office than to a home. Check the current MeLE Quieter DL price on Amazon; it was $389.99 and in stock on 30 October 2026. The 16GB/512GB listing we recommended before was not shipping that day.

CWWK four-port N100 and F8: best budget dedicated firewall

When you want four discrete ports instead of VLANs on a switch, this is the value leader.

The CWWK F8 is CWWK’s current four-port firewall. It has four Intel i226-V controllers, one DDR5 SO-DIMM slot, and a fanless 155 x 135 x 65 mm aluminium chassis with a heat pipe and room for an optional 80 mm fan. CWWK lists N100, N150, i3-N305 and Core 3 N355 builds. For routing, VLANs and a VPN tunnel or two, we would buy an N100, and that is where CWWK’s older four-port N100 box on Amazon comes in. Serve The Home measured that fanless four-port N100 platform idling under 10W after a couple of BIOS tweaks.

Stock decides which CWWK you buy this month. On 30 October 2026 CWWK’s US store listed the F8 barebone at $252.93 with the N100, $380.14 with the i3-N305 and $441.19 with the Core 3 N355, but all three showed sold out. Only N150 builds up to 16GB were in stock, from $393.33 barebone, oddly above the eight-core i3-N305. A four-core N150 adds little over the N100 for a firewall, so we would buy CWWK’s older four-port N100 box on Amazon at $355.91 today, or wait for the F8 N100 to return.

Who should buy it: the person building a proper firewall with WAN, LAN, a DMZ and a dedicated management or lab port, all physical. Four ports also make it a clean platform to install OPNsense or install pfSense and assign interfaces without compromise.

Where it falls short: support, if you want a vendor to call when something misbehaves. CWWK’s documentation is thin and its support is hit or miss, which is the price of the price. The barebone build also leaves you to fit your own DDR5 SO-DIMM and NVMe drive. Update the BIOS on arrival either way, because an early C-state hang bit some first-run N100 boards. Check the current CWWK N100 four-port price on Amazon before you pick a channel, since the store and Amazon prices moved independently all month.

Protectli VP2430e: best built-for-firewall box

Protectli sells the same idea as CWWK with the rough edges sanded off, and the VP2430e brings the line up to the N150.

The VP2430e runs an Intel N150 with four Intel I226-V 2.5GbE ports, one DDR5-4800 SO-DIMM slot and an M.2 NVMe slot. The fanless aluminium case runs off a 12V 5A adapter. Protectli’s knowledge base says it matches the VP2430 apart from dropping the 32GB soldered eMMC. Protectli also tested it with 64GB of RAM, although Intel’s sheet rates the N150 for 16GB. It replaces the J6412-based VP2420 we recommended before, which has left Amazon, so you get a faster chip and DDR5 with the same polish.

What you pay for is everything around the silicon. Coreboot firmware is an ordering option. Amazon carries a separate coreboot listing at the same price. The warranty is real, and support comes from the vendor rather than a marketplace seller. Extra M.2 E-key and B-key slots take Wi-Fi or an LTE/5G modem if you want cellular failover later.

Best fit: anyone who wants a firewall appliance rather than a project. You value coreboot and a vendor relationship, and you would rather pay more than troubleshoot a no-name board alone. It is the box we’d recommend to someone who will run it for five years and never want to think about the hardware again.

Think twice if: you’re optimizing for price per core. At $469.00 barebones on 30 October 2026 it costs more than the eight-core Qotom, and you still add RAM and an SSD. Stock is thin too: “only 14 left” on the standard listing and fewer on the coreboot one. So check the current Protectli VP2430e price and stock on Amazon before you plan around it.

Qotom Q10932G6: best for inspection and a segmented network

Buy this one when the firewall has to do more than route.

The Qotom Q10932G6 was the fanless eight-core six-port box from an established firewall maker that we found in stock on 30 October 2026. It pairs an eight-core i3-N305 with six Intel 2.5GbE ports, takes DDR5 memory, and ships barebone at $438.00 that day. Eight cores are what carry Suricata or Zenarmor inline without collapsing throughput, and six ports let you terminate WAN, LAN, DMZ, IoT, lab and management networks separately.

One caveat keeps this from being a clean recommendation. The Amazon listing names six Intel 2.5G ports but not the controller, and Qotom publishes no spec page for this model, so we could not confirm i226-V from the manufacturer. Ask the seller before you order, and check the controller on arrival with the steps in our i226-V fix guide linked below. Rovingclimber measured an i3-N305 firewall box idling around 13W and peaking near 50W under a sustained CPU benchmark, so expect more heat and power than the N100 boxes.

Who needs it: the homelab that runs Suricata IDS/IPS inline, terminates several WireGuard tunnels, and wants a port per network segment rather than trunking everything. Eight cores also leave room to run the firewall in a VM with a couple of services beside it.

Pass on it if: your network is a flat WAN plus LAN and you run no inspection. You would be paying for cores and ports you never light up, and support runs through the Amazon seller rather than a vendor help desk. Check the current Qotom Q10932G6 price on Amazon and budget a DDR5 SO-DIMM and an NVMe drive on top.

The box we would rather recommend here is CWWK’s six-port F5 with the new Core 3 N355, and it is worth watching through Black Friday.

The CWWK F5 documents what the Qotom does not: six Intel i226-V ports, one DDR5 SO-DIMM slot, two M.2 NVMe slots and a SATA port, in a 178.3 x 145.4 x 58.7 mm aluminium case with a copper-alloy heat plate and an optional 80 mm fan. The N355 build listed at $466.55 barebone on 30 October 2026, but every N355 and N300 variant showed sold out in CWWK’s US store that day, and only four-core N150 builds up to 16GB were in stock ($392.19 barebone). An N150 F5 makes sense for six physical segments without inspection. For IDS, wait for the N355 to come back rather than settling for four cores.

Netgate 4200: best turnkey, officially supported

Netgate’s 4200 is the answer when you do not want to build anything.

It is the reference pfSense appliance: a four-core Intel Atom C1110 at 2.1 GHz, four discrete 2.5GbE ports and a fanless case. pfSense Plus comes pre-installed, with Netgate support behind it. Because the company that writes pfSense also builds the box, it publishes numbers no generic vendor does. Netgate’s product page lists 8.75 Gbps of L3 routing over iperf3 (9.28 Gbps IMIX) and 8.61 Gbps with 10,000 firewall rules. IPsec with AES-GCM-128 reaches 3.2 Gbps, all on pfSense Plus 23.09.1.

Who buys it: the buyer who wants a sealed, supported product, or anyone deploying at a site where “call the vendor” has to be a real option. The lineup scales down to the 1100 ($289.00 on 30 October 2026) and the 2100 family ($599.00 and up), so there is a model for most loads.

Look elsewhere if: you want the most compute per dollar or you prefer OPNsense. The 4200 MAX costs $829.00 with TAC Lite, and an eight-core Qotom that costs about $390 less beats its Atom on cores. You are also committing to the pfSense Plus ecosystem. We haven’t linked an affiliate for Netgate; buy it from Netgate directly so the appliance arrives licensed and supported.

How to choose pfSense or OPNsense hardware

Five picks cover the common cases. If you are between two of them, these are the decisions that move the result, roughly in the order we would weigh them.

• Ports versus VLANs: a two-port box like the Quieter DL handles any number of networks through VLANs on a managed switch, which is how most production networks are built. Buy four or six physical ports only when you want a separate physical DMZ, isolated interfaces or a dedicated failover WAN, because extra ports cost power and money.
• Cores for services, not routing: every chip here routes a gigabit at line rate. Inline inspection and VPN encryption are CPU-bound. A four-core N100 or N150 suits routing plus a light WireGuard tunnel, while Suricata or Zenarmor at 2.5 Gbps wants eight cores. Cores are the one spec you cannot add later.
• RAM and storage: 8GB is comfortable for pfSense or OPNsense with packages, and 16GB leaves room to virtualize. Any small NVMe or SATA SSD works because the firewall writes very little, so do not overspend here.
• Barebone versus ready to run: a barebone CWWK is only cheaper if you already own a DDR5 SO-DIMM and an SSD. The Quieter DL and the Netgate arrive ready to power on, and the Protectli ships barebone but with vendor support behind it, so add parts and assembly time before comparing headline prices. The used route is an HP t740 thin client with a PCIe slot fitted with a low-profile quad-port Intel card, though the two together do not always cost less than a new four-port box.

One hardware detail deserves its own paragraph. The i226-V is the right NIC to want, but some early firmware revisions had a connection-drop bug where the link blips for a few seconds at random. The fix is well understood: update the board firmware, disable Energy Efficient Ethernet, and on stubborn units disable ASPM in the BIOS. On pfSense and OPNsense the ports appear as igc0, igc1 and so on. Our walkthrough on fixing i226-V random NIC drops on OPNsense covers how to confirm the controller from the shell and apply each fix. It is a setup step, not a reason to avoid these boxes.

Match the box to your connection and your services

Strip away the model names and the choice comes down to two numbers and one preference. The numbers are your link speed and how much inspection you want to run; the preference is whether you want to build or buy.

On a gigabit line doing plain routing, the MeLE Quieter DL is all the firewall you need, silent and ready to run, and a managed switch handles the VLANs. Step up to a multi-gig line, or add a DMZ and a few physical segments, and a four-port CWWK N100 is the natural home. Turn on IDS/IPS or terminate several VPN tunnels and you need eight cores: the Qotom today, or CWWK’s N355 F5 once it is back in stock. If you would rather not assemble anything, the Protectli VP2430e buys you a supported N150 appliance with a coreboot option. The Netgate 4200 buys you the official pfSense product with a vendor behind it.

Buy for the services you will actually run, not the throughput number on the box. Cores and ports are the two things you cannot bolt on later, so size those for where your network is heading. Let RAM and storage stay cheap, and judge any Black Friday price against what the cart showed this week.
