I agree. I have a CM 690 and it's an excellent mid tower. Comes with 3-120mm fans (front, back & side) and if that is not enough, up to 5 additional fans can be installed for increased ventilation: 2-120/140mm on top, 1-120/140mm on bottom, an 80mmx15mm on the right side (provides air under the mobo), and a second 120/140mm on the left side. Decent cable management and tool-less drive bays and expansion slots for under $57.
