the chieftec case is extreme nice, you can mount 80mm fans in front of the hdd, you can also mount a 120(!)mm fan at the back, i sugest a noiseblocker ultra silent 120mm fan(you cant hear them at all if you run them at low speed), silent&cool so case tempreture==room tempreture most time. it also has 2 holes in the side. you can get many additional stuff for it like transperent sides, the transperent sides also have a 80mm fan.
and the case looks norble/professional and is also a bit bigger than normal midi towers but smaller than big towers, so you have enugh room.
i purchased my stuff online at various stores using a price search.
