Did a search for hardware compatibility for ASRock AD2550R/U3S3 Mini ITX Server Motherboard and found one reference from 2013.  Sounds like the board will work for unraid but before I get it, I'd like to know if there is anyone with  more recent experience with this MB.

 

The primary reasons this one interests me is it's low power usage and price.  Additionally, the enclosure I have is mini ITX.

Thanks in advance.

 

EDIT

Thought  it might be useful to add that this is going to be a simple home file server. May want to add the plex plugin later.

I picked this MB for the same reasons, given about a $150 price for the MB and an onboard atom processor.

 

The good things are: 

  several SATA3 ports, and a couple of SATA2 (seven total, I recall). 

  Onboard USB port for OS

  small size for any case

  PCI for 4x Sata3 expansion card.

 

Ram is topped out at 4GB with two 2GB laptop chips.

 

I'm running sab, cp, plex as docker containers, plus apcupsd/powerdown (works) and unmenu as plugins.

 

Unraid 5.05 and b6 boots fine from this.  All of the onboard sata connectors work.  I've just ordered the sata3 card with a Marvell chipset.  I think the front USB panel works, but I haven't gotten S.N.A.P. running yet.

 

I haven't been able to get the bios to temp control the fans (they run full all the time and I have unplugged them).

 

Overall I'm pretty happy, but given all the $$$ I've spent for case and drives and drive mounts I think I'd have been happier with another $100 spent on a snappier chip. 

 

She will stream 1080p fine to one client even if mover or parity is running.  However, she struggles if I am copying something through SMB the same time, or uploading and trying to get OSX finder to display contents of a large directory at the same time.  Getting the server set up and copying a bunch of drive contents to the array we've been watching a lot of stuttering video the last few weeks.  I haven't tried streaming two HD vids at the same time but I suspect it could be an issue.

 

I haven't had any trouble with sabnzbd downloading at 2.5 mb/s and streaming.

 

Overall, it works, but you get what you pay for. A low end chip might become the weak spot in an otherwise great system.
