Don't go near Coolermaster modular PSU's, got bad reviews in Custom PC magazine (I know ive got one, but didnt know they were bad but oh well haha). Be Quiet! Ones are supposed to be spot on, aswell as corsair ones I think it is. Get yourself some decent thermal paste like Artic Cooling MX-3 paste, pisses all over the Artic Silver 5 and it doesnt contain elements that conduct electricity either so you don't short things out if you accidentally get some on the board. With the paste, stick literally a gnats chuff's worth on, wack the cooler on, give it a twist a bit to spread it about, then secure it down. Look up how to apply it to your specific CPU as cores are arranged differently on some CPUs. Too much paste will give you the opposite effect your after and can insulate the CPU. Cooler to go for at the moment is the Titan Fenrir. Id go for a Samsung Spinpoint F3 1TB hard drive also, they are bloody quick and cheap (£60ish) Another thing I couldnt live without is a dedicated sound card. Creative Fatality gaming one is the one you want to go for. I'd also go for a Coolermaster CM-690 gaming case. Pretty much rated one of the best around as it has bloody good cooling, is cheap, also the option of a nVidia version too. Can also take all different sizes of fans. Has 2 roof, 2 side, 1 other side, 1 bottom, 1 back and 1 front. Got this case myself, can hold the biggest graphics cards with ease and has tons of room to route cables. What it can look like inside this case, old photos and its changed now but you get the picture.
