I know it has been said already in this thread but I'd like to express my love for the Corsair 540 air case. By far the easiest build I've ever done. There are two special trays to snap in a ssd or hdd. The motherboard tray has a center pin to make sure all the screws line up. Even attaching cpu cooler bottom brackets like the 212 evo is a breeze as the motherboard mounting tray is open right over the CPU. The hardest time I had was sliding in my DVD drive in one of the 5.25" bays, but it wasn't too bad. I can't think of another case I'll use in a long time.
