A very nice, clean looking M-ATX tower that's easy on the wallet. Also has front USB 3.0 ports. It's designed for positive air pressure (less dust buildup) and acoustics (quieter).
RRP usually $90, at $59 it's a good deal for a silent HTPC (or shuttle PC, whatever you wish to call it) case that has enough room to fit in a gaming GPU and up to six HDD's.
Good price, but SPCR preferred the similar, less pretty SilverStone Temjin TJ08-E. If buying just one and lower noise/better cooling was a priority, I'd be thinking of it in terms of maybe $10 extra/year, rather than 60% more.
