I want to build a unit to use as an mp3 audio player in the lounge/tv room. Obviously need it to not look like a computer and not looking for a 'Media Centre' as no video capability is needed. My thoughts were a 7" touch screen, low power mobo/cpu, mini/micro atx case, hard drive, wi-fi and a dedicated sound card. Case is not important as i could build this from scratch Has anyone tried something like this or got any suggestions for hardware etc? What would be a suitable OS for this? Nothing too overkill. Would something like an intel atom all in one cpu/mobo be suitable?
