The above build is along the right lines, but I have a few issues...
Motherboard: Recommend ASUS P8Z68-v PRO GEN3
GPU: OK, certainly grab a 7970 on your budget
PSU: Not sure what price this is at, but I certainly wouldn't want to pay much extra for the 80PLUS Gold. A 850w Corsair, Sea Sonic, Antec or XFX unit would be my recommendation. Modular cables ideally too. Anything Bronze or above would be fine.
Case: Fully Tower..? No need....A nice Mid-Tower case would be plenty. There's loads about, take your pick
SSD: OK, also take a look at Intel Series or Crucial M4
SerialKiller I have used the noctua before and am pretty set on a water cooling build. Also thanks for the advice, the 7990 and motherboard you suggested will probably be added and I will look at the other SSD's you mentioned thanks for the advice
That's actually not a bad prebuilt WC loop. I would personally want a different radiator and not use the premixed coolant (distilled water is the best, cheapest, most convenient and least troublesome). However, it's got a solid pump and block which is where most of those prebuilt loops fail.
If you're dead set into the watercooling, consider posting in the WC forum (under the Overclocking section) and we can help you out. There's a few guys from the UK that are regulars, so they'll have more relevant info than I would (USA).
Dunno why everybody is against full towers. I personally like the size (yes, it is huge) but I can't work in a mid tower - not enough room for me, my components, and my watercooling stuff. If you can go see one or measure out the physical dimensions I would recommend it - they may not be for everyone but that doesn't mean people don't want them
1050W is overkill for almost anything. It really depends on the GPU, but I'm agreeing with the solid 850W recommendation (AX850 comes to mind immediately).
Thanks for all the advice and I'm dead set on a full tower as I have used mid tower cases before and like boiler said not enough room to work with and that was without water-cooling and as this one is definitely a watercolour build I think I'm going with a full tower, so saving money on the PSU is a good idea. I already have 12gb of corsair vengeance RAM so I didn't include that ad I have a western digital caviar black 1tb, however do not have an SSD so that is something I'd like to test but just for the OS, thanks for all the advice guys
