So here's what I'm looking at getting: Warning: Spoilers inside! The parts I'm 90% sure on. Case: Coolermaster Storm Enforcer Mid-Tower, I think this case is pretty much final for me. It has everything I need/want and it's quite cheap and looks nice too. Hard Drive: 2TB Western Digital Caviar Green SATA 6GB/s, Again I think I'm pretty much certain with this choice, I just wanted a cheap 2TB WD drive, it's SATA 6GB/s as well. RAM: 2x2GB Corsair DDR3 XMS3 Classic 1.50v , It's either these or the Gripjaws, I made sure it was 1.50v as I heard there was some issues with RAM that had a voltage higher than that with Sandy Bridge CPUs (Apparently 1.50v is the recommended.) CPU: Intel i5 2500k, This is a certainty, I can overclock this a fair bit too from what I have read, although I would imagine I will need to buy another CPU fan as the stock one would not suffice. The parts I'm really not sure on. GPU: Here I'm stuck between the 1GB XFX Radeon 6870 Black Edition, the 2GB XFX Radeon 6950 which is £50 more but from the benchmarks offers performance gains of about 20%~ and the 1GB MSI GTX 560 Ti. I'm leaning towards the 6870 at the moment. PSU: I really have no idea on this, I might end up doing CrossFire or SLI though. I just choose this on a guestimate, Corsair Gaming Series GS700 700W. I don't think I need more than 650W. Motherboard: I'm stuck between the Asus P8P67 LE Rev3 and the MSI P67A-GD53 (B3), it'll most likely be the latter. Now for the questions: My GPU needs something like two 6-pin cables that attach to the Motherboard and in an unboxing video of the 6870 I saw that it doesn't come with these, where can I find them? Is there any other cables I will need? Like SATA power cables or a 6GB/s data cable for my HDD?
