you see them like in business..like costco's optometry center..
but they are like 3" thick 8" deep and 8" wide. when your limited on space.. it does everything a normal tower does but just more compact. SHOOT. I just cant figure it out. but i dont know if HP has them and the ones I saw @ costco were Dell's but I look at dells website... and cant find crap. wt-****
I personally prefer the Silverstone SST-LC12; however, shed caution on the thermal output of your proposed configuration as the case cannot take much heat.
