I am planning on building a semi-budget gaming rig and really like the HAF 912 for my case. However I also like the variant on this case the Storm Enforcer. Cooler Master currently has a refurbished version on their site for cheaper than the HAF 912 here. Normally I would be wary of refurbished items for a computer, but this is the case not a critical piece of hardware.
My question is how reliable is Cooler Master with refurbished cases?
Side question regarding the Storm Enforcer. It comes stock with 200mm front fan and 120mm rear fan. this setup insures positive air pressure in the case. There is also a slot for a 200mm top exhaust, which would put the case in negative pressure right? Will this cause a ton of dust build up, or am I over thinking the fan pressure situation? (will be using a CM Hyper 212 evo as well if that changes anything) Compare this to the HAF 912 that would allow 200mm top and front, 120mm back, and 140mm side. This would maintain positive pressure with a side fan that provides excellent cooling ive read.
Either case should be great but I think you are over-thinking the fan situation, cool air blows in and warm air blows out. No need to worry. Correctly installed, the Hyper 212 will keep the cpu cool and the positive/negative pressure situations usually only apply when water-cooling.
Get the hyper 212+ and use the extra money towards something else such as another fan. You will need 2 intake fans (I suggest cougar fans) for the HAF 912 and remove the top drive cage for maximum performance.
