Hi folks, I need a new case and currently, the Silverstone Fortress FT02 is my favorite. Thats because its elegant, can be both quiet and performant, and has positive air pressure; I dont like dust. To be completely awesome, its lacking a removable motherboard tray, but as long as its got enough space to work with contrarily to my Antec P182, I should be fine. The one thing that kept me from buying the FT02 is, that it doesnt get along with my CPU heat sink the Prolimatech Genesis , as the TDP (Thermal Design Power) of the Genesis will decrease from 360W to 100W if rotated by 90 degree, according to the engineers of Prolimatech (I wrote them an email). Unfortunately, 100W is not enough for some OC. Found no better case, so I'm now looking for a heat sink which works fine in the FT02. What do you think about the Prolimatech Megahalems Rev.C? Its heat pipes are orthogonal to gravity inside the FT02, unlike the heat pipes of the Genesis. So, there shouldnt be any drop in TDP when the sink is rotated. I'm unsure whether or not the heat pipe orientation of coolers like the Thermalright Silver Arrow causes performance problems inside the FT02. I want to continue to OC my CPU between 4.4GHz and 4.8GHz. My current system is: MB: Asus P8P67 Evo CPU: i7-2600K CPU heat sink: Prolimatech Genesis with two 140mm be quiet! Silent Wings USC fans GFX: Radeon R6870 Hawk by MSI PSU: be quiet! 550W Dark Power Pro (got an older revision than the one linked to) Case: Antec P182 with two intake and to exhaust 120mm fans RAM: 4x4GB low profile DDR3 plus an SSD, two HDs, 16GB of low profile RAM, one DVD drive. I'm going to add a Lamptron FC5 V2 to my system. Cheers.
