I'm planning to build a NAS sometime this calendar year and I'm stuck on the motherboard. I'm pretty set on the rest of my build, I just need a decent motherboard suggestion. Needs: Micro ATX or Mini ITX support for ECC memory at least 8 SATA ports (the more the better but I can be flexible on this) at least 1 PCI Express 2.0+ x4, x8 or x16 slot (the more the better) hardware RAID not needed embedded CPU a plus, but not a need on-board graphics (I don't want a discrete graphics card) I had a motherboard picked-out, but after reading the reviews on several sites, it sounds like that model consistently fails after 18-24 months; that's just not good enough. The motherboard that I had picked so far was the ASRock C2550D4I Mini ITX Atom C2550 Motherboard. This motherboard just seemed too-good-to-be-true and I guess it was. Notes: I'm ok with having to add a PCI-E card to expand that SATA port count if necessar I don't care about RAID as I'll be using Windows Storage Spaces to allocate my files over my drives. I'll be setting up the equivalent of a mirrored RAID to get 16TB of effective storage. My motherboard doesn't have to have an embedded processor, but that would be nice. Passive cooling of the processor is ok too, as long as it's an ATOM or something, as my case will have great airflow. This NAS won't be doing any heavy lifting, just serving files. I have a HTPC that plays my content and a gaming/development PC that does my encoding and whatever else. PC Part Picker List: I've put together a PC Part Picker part-list that has the above mentioned motherboard in it, but I plan on replacing it with a better suggestion. http://ca.pcpartpicker.com/list/hDwjWX If you don't want to view the list on pcpartpicker.com, then here's the component list: (1x) ASRock C2550D4I Mini ITX Atom C2550 Motherboard (1x) Crucial 16GB (2 x 8GB) DDR3-1600 Memory (1x) Samsung 850 Pro Series 256GB 2.5" Solid State Drive (4x) Western Digital Red 8TB 3.5" 5400RPM Internal Hard Drive (1x) Fractal Design Node 804 MicroATX Mid Tower Case (1x) Silverstone Nightjar 520W 80+ Platinum Certified Fully-Modular Fanless ATX Power Supply (1x) Microsoft Windows 10 Home OEM 64-bit (2x) Fractal Design FD-FAN-SSR2-120 40.6 CFM 120mm Fan (3x) Fractal Design FD-FAN-SSR2-140 66.0 CFM 140mm Fan (1x) Tripp Lite SMART1500LCDT UPS (1x) Mediasonic USB 3.0 PCI-E Card
