The D5 pump should be able to handle a loop with 3 blocks, I use the weaker DDC pump in mine at it handles a 2 block loop without any problem.
Found Alphacool's kit, didn't notice it earlier:
http://www.frozencpu.com/products/17360/ex-wat-227/Alphacool_NexXxoS_Cool_Answer_360_DDCXT_-_Kit.htm...This kit have as I mentioned above a nexxxos rad which currently is one of the top rads, while the kit looks like bunch of cheap stuff the performance is top class. Though the fans aren't that good. And the ddc doesn't have any top nor a good way to mount. Anyways, the 2 kits should perform very well, the XSPC is the silent premium and the Raystorm looks gorgeous in case, and the Alphacool is the ugly high performance kit. Also take a look at EKWBs kits, the supremacy one should perform at the same level as well. Between these three companies it is all about preferences.
