Pros: I have built about 15 computers and this has been one of my favorite cases. The HD bays are completely tooless, as are the mounting points for the cards. Even the CD was tooless. This makes changing out parts very quick. More importantly, the layout of the case made putting a PC Power and Cooling PS in a snap (its not ATX, its bigger), and the two 8800GTS-512's in SLI fit. I particularly liked the organization of fans which are quiet. I do suggest buying two more quiet 120's as they make almost no noise. I have four of these fans in this case and they whisper. I like how two fans exhaust out the top quietly. The excellent air flow keeps the video cards cool - nothing gets hot including the hard drives. The whole computer is quiet.
Cons: I thought the bright blue front fan was a bit too much so I took it out. I just let the four fans suck air through the front opening. THERE IS NO SPEAKER. Since I was replacing a case, I stripped the old one out, but I don't know why Cooler Master skimps on this. Maybe this is the new standard. Without it, where's the beep.
