Came across this mod of a Mac mini. http://www.siivel.com Interesting but not cheap. He sells some of the parts separate on eBay though. I was more interested in his vented base. But I think it will be too noisy when the fan runs at 100%. Take off the base of the 2012 Mac mini on its side when the CPU and fan is running 100% (say on Handbrake) and there is a noticeable noise difference. I think it would also suck in too much dust.
