water cooling the cpu is cheap and quiet, the 8 fans for everything else are loud as fuck though!

 You should try BlackNoise fans. I have few of their NB-BlackSilent Pro 120mm fans installed in my rig along with Noctua NH-U12P SE2 CPU cooler and I can't even hear when my computer is on. They also push a lot of air, have 6 years warranty and all the German quality and technology packed in them.

 they look pretty sweet!

I've managed to make this pc unstable anyhow, so i may break it down and sell it in bits and build another one

 there where pre tubed, and the wiring mess is hidden in the case, simples.

 ah sounds good and true good idea !

 tubes are watercooling for the cpu, cables at the bottom are the powersupply. They're pretty easy to understand really

 Is it connected to a chiller or something? What are the cables wrapped in? Arent you scared it may leak!?
Yeah i bet. Only really used to laptops though.

 Theres a radiator in the roof of the case with some fans moving the heat away

 its the same as building bikes, it has to be a bit custom and it has to be the best you can possibly afford, lol

 it is, have just changed it to an nvidia 790 ultra though, to get the two gtx295 to sli properly (it runs hot though and i've had a pain of a time getting it to boot and run stable). The republic of gamers mobo was a last gen maximus extreme, that ran ddr3 ram, has an lcd poster and soundcard, and built in watercooling blocks, its also for sale now....

Specs are:

Coolermaster 690 case
intel exreme quad core 3.0 ghz
8gb kingston hype ram
gtx 295 graphics cards in sli (quad sli, its epic)
nvidia 790 ultra sli motherboard
kingwin 1000w psu
watercooling for the cpu
bitfenix spectre fans
bitfenix fan controller

bout it really

 What parts do you have for sale buddy?
Also quad SLI that is insane , you could control sattelite's with it.

 I've got The asus motherboard for sale is all. socket 775, maximus extrreme, ddr3, crossfire ready, with soundcard, backplate, lcd poster etc. all in perfect condition.

I've also got my old spare gtx 295 i suppose, but its currently not working, need to try it in another pc to double check

 What you after for the motherbaord pal?

 ~£150 ono

 nope, not that fancy

The rad, pipes and cpu block are pretty similar, but the res and pumps are much cheaper..
