"Perfect Media Center PC"4.5 starson by reng2005
Pros: Cool looking -- nice, clean, elegant.
Small and unobtrusive -- will look great on my TV stand.
Plenty of processing power; pretty decent (discrete) graphics.
Easy hook-up to my plasma television and AV receiver (via TOSLINK).
Cons: No optical drive (but it's not really a big deal).
A bit expensive (but worth it for the gorgeous industrial design).
Summary: For me, this is the perfect media center PC. I already have a Blu-ray player, so I don't need a DVD drive in the Mac mini. I have a Windows 7 machine as my main PC and the Mac mini will stream content from it.
