Building a killer NAS or home lab router starts with one critical decision that most people overlook until it is too late: the motherboard. Pick the wrong one and you are stuck with no PCIe slots for your 10GbE card, no M.2 options for your SATA expander, and a WiFi 7 card gathering dust in a drawer. Pick the right one and your entire home lab ecosystem clicks into place like it was always meant to be there. Whether you are eyeing the ASRock N100M like the Reddit community has been buzzing about or you want to explore what else is out there, this guide breaks down the best NAS motherboards available right now so you can build with confidence.
What to Look for in a NAS or Home Lab Motherboard
Before diving into specific boards, it helps to know what actually matters. For a NAS or router build you want to prioritise low power consumption, multiple M.2 slots, at least one PCIe slot for add-in cards like a WiFi 7 adapter or 10GbE NIC, and solid SATA support. ECC memory support is a bonus for data integrity. Fanless or passive cooling compatibility is also worth considering if you want a silent build.
Top 5 NAS Motherboards for Home Lab Enthusiasts
1. ASRock N100M (Best Budget All-Rounder)
The board that sparked this whole conversation. The ASRock N100M is built around Intel’s efficient N100 processor and packs a surprising amount of connectivity into a Micro-ATX form factor. You get a PCIe x16 slot (running at x4 electrically), two M.2 slots, and multiple SATA ports. This makes it an excellent candidate for dropping in a WiFi 7 card, an M.2 SATA expander, and even a 10GbE M.2 NIC all at once.
Pros: Extremely low power draw, affordable price point, solid connectivity for the cost, passive cooling friendly
Cons: PCIe slot runs at x4 speeds not x16, limited RAM capacity, no ECC support

2. ASUS Pro B660M CT-HM (Best for Power Users)
If you need more headroom and are willing to spend a bit more, the ASUS Pro B660M delivers Intel 12th Gen support with multiple M.2 slots, PCIe 4.0, and ECC memory compatibility. It is a strong choice for a NAS that doubles as a light virtualisation host running Proxmox or TrueNAS SCALE.
Pros: ECC memory support, PCIe 4.0 speeds, multiple M.2 slots, great BIOS
Cons: Higher power consumption than N100 builds, more expensive, larger footprint

3. Topton N5105 Mini ITX Board (Best for Compact Builds)
Popular in the home lab community for router and NAS combo builds, the Topton N5105 board offers quad Intel 2.5GbE ports onboard, M.2 slots, and a fanless design option. It is a favourite for pfSense, OPNsense, and TrueNAS Mini builds where space is at a premium.
Pros: Quad 2.5GbE onboard, compact ITX size, very low power, fanless options available
Cons: Limited PCIe expansion, sourced mainly from AliExpress so shipping times vary, less community documentation

4. Supermicro X11SCL-F (Best for Serious NAS Builds)
When you are ready to step into proper server territory, the Supermicro X11SCL-F is the gold standard. It supports Intel Xeon E processors, ECC UDIMM RAM, IPMI for remote management, and multiple PCIe slots. If uptime and data integrity are non-negotiable, this board earns its place.
Pros: IPMI remote management, ECC support, enterprise grade reliability, excellent TrueNAS compatibility
Cons: Higher cost, louder and more power hungry, overkill for simple NAS use cases

5. ASRock J5040-ITX (Best Passive Fanless Option)
For those who want a completely silent build, the ASRock J5040-ITX uses a soldered Pentium Silver J5040 processor with a fully passive heatsink design. It has two M.2 slots, four SATA ports onboard, and a PCIe slot for expansion. Perfect for a bedroom or living room NAS where noise matters.
Pros: Completely fanless, four onboard SATA ports, affordable, compact ITX form factor
Cons: Older processor architecture, limited performance ceiling, no 2.5GbE onboard

Frequently Asked Questions
Is the ASRock N100M good for both a NAS and a router?
Yes, the N100M is a solid dual purpose board. Its PCIe slot can accommodate a WiFi 7 card and the M.2 slots can handle a SATA expander and a 10GbE NIC simultaneously. It is one of the most flexible budget options available right now for exactly this use case.
Do I need ECC RAM for a home NAS?
ECC RAM helps protect against data corruption from memory errors, which matters more as your storage pool grows. For a casual media server it is optional. For a business critical or large capacity NAS running ZFS, ECC is strongly recommended.
Can I run TrueNAS or Proxmox on these boards?
Absolutely. All five boards listed here are compatible with TrueNAS SCALE, Proxmox VE, or Unraid. The N100M and J5040 are particularly popular in the TrueNAS community for their low power efficiency.
What WiFi 7 card works well with the ASRock N100M?
The Intel BE200 is a popular and affordable WiFi 7 card that fits the PCIe slot on the N100M. It supports the 6GHz band and delivers excellent throughput for a home lab router setup.
Best Overall Pick: ASRock N100M
For the majority of home lab builders looking to run a NAS and a router without breaking the bank, the ASRock N100M is the clear winner. It strikes the perfect balance between connectivity, power efficiency, and price. The combination of a PCIe slot for WiFi 7, dual M.2 for SATA expansion and 10GbE, plus onboard SATA ports makes it one of the most versatile budget motherboards on the market. It is not perfect for enterprise workloads but for a home lab it punches well above its weight class.
