The Cooler Master Cooler Master Elite 430 was brought to my house by UPS today for a friends build. Its pretty sturdy and well fit. Painted inside and out with a nice window. I was impressed for the price.
The only thing i noticed was its fairly bare as far as cable management goes. the motherboard tray is touching the back side of the case. But that can be worked around.
Its plenty wide enough for a CM 212 air cooler. Needs a second 120mm fan on back thou.
you will need a case at least 7.5 in wide for the 212 to fit, and the CM elite 430 is. It also has spots for up to 5 fans. I've used a few different $40 cases and the coolermasters are some of the nice ones at that price
