How much are you willing to spend to have a "cool" system?
Do you want to go with two all-in-one systems to water cool your cpu and gpu?
If you are willing to buy individual parts for a custom cooling setup, you could also water cool your memory.
The main issue, other than price, is do you have room for the radiator(s) inside your computer case and if not, are you willing to mount a radiator outside of the case?
Hot pink would be cool (pun intended), but it's really up to you as to which colors you like best.
Are you aware how much work is involved to sleeve cables? And how much it hurts?
Send a PM to Boondocks and ask him to reply in this thread as to how long it took him to sleeve his power supply and fan cables.
Boonie can also advise you as to what worked well in his water cooled systems and he posted some pictures of his water cooling results.
Have fun and be sure to post pictures of your results.
