Hey Cakewalk, I need to ask you for some direction due to your experience with antec and asatek pump blocks and custom loops: How much time should I spend trying to match up the diameters of the pump blocks and tubing/fittings in order to keep good, consistent flow rates? Does it have a large enough effect to matter that much? I was laying out all of my stuff and noticed the inside diameters of the asatek dual cpu/gpu unit versus my Antec kuhler 920 reguarding the in/out on the pumps and rad's. Should the barbs on my res exactly match them? And should the tubing be larger or the same size as the stock black tubing? Also, I have the option of using a dual dvd bay res or a swiftech micro res so which would you use and/or which is better? Thanks a million! Just want to make the best decisions fort the loop before putting her together. Heres the loop:
Crossfire 6850/5870 using the dual cpu/gpu asatek pump blocks for them-modifying the cpu one to fit 6870.
120 by 49 rad in dvd bay -- another 120 by 49 rad in hdd/dvd bay (its going in a Xigmatek Elisium case with both drawing in cool air from the front)
Either dual bay res or swiftech micro res

I modified to work on my mobo because of the need for better cooling.(MSI 990fxa-gd80)
I am also going to put these on my gpu's to help with cooling the ram,etc... http://www.newegg.com/Product/Product.aspx?Item=N82E16835708009
Any advice is very much appreciated!!
