Re: Watercooling for the ultimate $1,500 system
With regards to case size and radiators.....it basically comes down to how far do you want to overclock, and how quiet do you expect it to be? If you want the absolute limit in cooling and overclocking, you need a good sized rad...likewise if you hope to run fans at 7V in quiet mode, it'll work much better if you can run a pair of 120mm fans, rather than a single. A dual 120 requires a fairly big case....or else modding.
The DD12V is a good pump, high pressure so it'll work well with your TDX. Are you sure you want to watercool your NB? It'll decrease the flow and cooling to your cpu, unless you are going to try for extremely high FSB (250 is fairly high imo) the NB limits overclocking more often than it helps.
Watercooling your GPU helps as well, but really you want to keep the same kind of blocks in use in the system. The TDX is a low flow, high-pressure block. The Maze-based blocks are high-flow, low pressure...which means that while they will work together, it won't be as effective as if you were to stick to high-pressure blocks.
Basically it comes down to what you are willing to do, and what you are willing to put up with.
