And two optical drives and a hard drive Now here comes the troubles i have no idea what Cpu cooler will fit in this form factor and still allow Stable Overclock to something like 4.7Ghz (Maybe thats too much i dont know whats stable for 24/7 use) I want to have the ability to overclock both the Gpu's (I put in a second Gtx Titan but thats not gunna be part of the rig right away) and Cpu but i dont know what overall cooling i should use and how it would all fit I'm willing to change the case fans power supply Ect if someone could help i would appreciate it
P.S. I would also like a thermal paste recommendation
