As far as the AC blocks go, they are around $80-100 which is similar to most koolance/EK/swiftech/enzotech products.
The full-cover GPU blocks are around $115 a piece, while the competition is usually between $80-130.
Their radiators are very expensive, and they dont seem to be as much better than they are expensive. For this reason, I plan on using alphacool/ek/swiftech. All 3 seem like good options.
And to sum thing up I guess I will get into pumps, this area is giving me the most trouble!
Here is a post I put on OCN:
"So I used martins spreadsheet, put in the following:
-AC Kryos XT-Thick O-ring (plan on using the cuplex kryos HF, but that wasn't avalible in the file so I used this instead assuming they would be similar, both will be using thick o-rings)
-2 AC Aquagraphix480s (plan on using the 680's)
-2 xspc re360's
-2 90 degree elbows
-8 compression fittings'
ALL IN SERIES
I also plan on using an ek ram block for the corsair dominator, because I might oc my ram at some point and this is an inexpensive block specially made for the ram I would like to use.

His estimate seems to tell me I need more pump than the general guidelines in this thread suggest, and more pump than most places suggest. The only single pump that would put me in the "sweet spot" is an Iwaki RD-30 at 24V, which is a monster. There are dual pump options too of course. Do you guys think a build like this would require that much pump?"
