Well if you want dust to hell, then yes. I would keep the sides on but put 3+ high speed 80mm fans or a couple 120mm fans to keep it a bit cooler in there.
ok, i looked in my bios and it said that my cpu temp was 40 degrees C and my MB temp is 31 degrees C. is there some desrepency between that and speed fan? please help me? which one is right? should i be concerned?
