I recently purchase this unit to run openELEC which is a stripped down linux install that only contains XBMC.
The guts of it are: Dual Core Intel Atom D525 (1.8GHz) with ATI Mobility Radeon HD 5430, 512MB GDDR3
I put 4GB of ram in it and a 4GB USB flash drive and it runs pretty darn well with a total cost of $135. It streams my 1080P mkv blu ray rips perfectly to my TVs.
I use JRiver MC, mostly for music and Gizmo on my main PC. This unit got me thinking that with a small SSD and windows OS that this could be a great theater view machine with JRiver installed. Silent (fanless form factor) small, built in IR. I use the current one to stream to TVs that have audio only from the TV itself. I'd use jriver in the theater where I have 7.1.
I would continue with XBMC with this, but it currently can't decode the DTS-MA codec and my current receiver can only accept LPCM in 7.1. Would this PC have enough horsepower to handle that? I don't want to shell out another $150-200 without knowing for sure.
Thanks a bunch!
