Quiet and efficient
I bought this PC because my motherboard was out of order: I installed my old hard disks (one SSD and two HD) and my old video card without a hitch, cloned the SSD to the SSD-Me, and got a GT710 and a keyboard/mouse pack.
Everything works perfectly and silently, with more than respectable performance for my use.
Only complaint (inherent to ASRock): you have to stop using drivers on CD, nobody has a drive any more :)
