Originally I only had 10" sub on bench with poweramp in.
With some modification I could fit the VoomPC right next to poweramp. (Seen upside down. WIP. Best picture I had)
No fans. Heat dissapation is not great, but power is low due to Solid State Disc. If I get problem I might let the PC and poweramp stand on a copperplate screwed to chassies. But no problem yet.
Small items like the USB soundcard is placed where CD changer used to be.
