The 300R windowed version is a great starting platform for any system. dual 120mm fan/radiator mounting spots in the top and front bezels, with 120mm exhaust points located on the back IO panel and on the floor of the case.
With few cable management holes, Corsair did a great job at the placement of the holes and zip tie marks which provide optimal management potential.
The Cooler master HAF 932 is also a pretty good starting case. With a LOT more space than the 300R, the HAF 932 allows for E-ATX mother boards (extended) and either top or bottom placement for PSU. With as few cable management holes as the Corsair 300R it doesn't really have a gain in cable potential..
But the HAF has HUGE airflow potential. (High Air Flow) with 200mm fans included on the front top and side panels.
But I'll have to recommend something a little better.
