I am looking to build a Steam OS box, I would like to run 'light' native Steam OS games and stream the rest from my powerful windows box.
What are my options for a motherboard that fits the requirements listed and (with a case/CPU/RAM) is close to 400 USD?
Valve Min Requirements (ref)
- Processor
- Intel or AMD 64-bit capable processor
- Hard Drive
- {Support for} 500GB or larger disk
- Video Card
- Intel, NVIDIA, or AMD (RADEON 8500 and later if AMD)
- Additional
- UEFI boot support, USB port for installation
My Requirements
- Quiet
- Above everything else this box must be whisper quiet. The Box is better if smaller but does not need to be tiny. For the Mobo it's CPU should be able to support a custom cooler that is quiet.
- Built in Wifi AC and Gigabit NIC
- I would like to use my existing wi-fi ac for now (even though it works poorly) and later cabled ethernet when I get the time to do reno's. I plan to stream 4k if possible from my windows box.
- Built in HDMI 2.0
- As mentioned before I would like to have a 4k TV and even if the steam can not handle fast refresh rate I would like my box to be able to provide the capability. (Display port would also be nice.)
- Built in USB 3+
- Having 5+ USB ports (/w 1+ as USB 3) would be helpful
- Built in Blue Tooth
- Helpful as I can see a lot of input devices using BT in the future.
- Built in Surround Sound
- Surround sound capability, 7.1 with 3.5mm jacks on the mobo preferred.
- Ability to upgrade
- SSD M.2 upgradability would be nice
- The ability to swap in a decent sized PCIe video card.
- The ability to have 16 gigs of RAM
Additional Information
From what I could find Valve does not have a compatible hardware list but because Steam OS is built on Debian I would rather use hardware that has a good track record of working on Debian if possible. On the flip side I would like to use newer lower power (14nm) hardware if possible as I intend to leave the box running. If all fails I may opt for the Steam Link and later go for a Steam OS box.
UPDATE: I prefer to build the system and install Steam OS myself. I have modified this question to refer to only the motherboard, once that is chosen I will add a question for what case/CPU/RAM works best with it because they are quite dependent on the motherboard selection.
