black ice pro... nuh-uh! get atleast a black ice extreme (thicker version of pro - dissipates twice the heat)
and the dual 6800's - they dump ALOT - i mean ungodly amounts of heat into the loop - one BIX will NOT handle the heat load that these will put out
for the cards, i'd suggest mounting a black ice extreme II in the floor of your case, as it is raised off of the floor - and for the dual GPU blocks - get the acetal low-profile version of the Maze4 - its much lighter than having a chunk of brass on your card, plus its designed for the SLI boards, so you don't have the water block resing on top of the card below, and it provides equal performance, as it uses the exact same base as the normal maze4 blocks
then for the CPU & chipset, i'd suggest mounting a second BIX II in the top of your case
and don't even bother with a resivoir... or in your case, two of them - use a t-line - it'll be alot more compact, and use alot less tubing in a setup such as yours
plus a res does nothing but take the velocity of the water from X to zero, creating more work for the pump, decreasing the overall flowrate of the loop in the longrun (res restricts flow)
i'd also suggest using 1/2" barbs/fittings and 1/2" ID x 3/4" OD (1/8" wall) tubing for your setup - and use clearflex60 - its MUCH cheaper than tygon in large volumes (89cents/foot @ jab-tech.com for 10+ feet), and has a bend-radius, and anti-kink properties near that of tygon, and with the larger ID, flowrate through the loop(s) will be much greater
and the pumps - the DDC's are great pumps, and have a great amount of friction head, but lacks in the flowrate - because of this, i'd suggest a Laing D4/MCP650 - they're still very small pumps, they run on 12v DC, and they have 1/2" fittings (less restrictive), they have a slightly lower friction head, but that is compensated for by the flowrate that they provide - just over 300gpm
