Alright... I did this my self, and I’m actually adding a chiller to mine, so I may be able to help you out. You'll probably want a Lang DDC (Swiftech 350, ect) for you pump, and the Swfitech Micro Res if you don’t want to use one of your bays. I'd suggest trying to mod the pump, because it helps performance ALOT. Plan on using 3/8" tubing (what this pump is designed for) because there is precious little space in this case.
You blocks on your CPU and GPU, well, it's whatever you like. Danger Den, or Swiftech. Personally I went with Swiftech gear.
Then we get to the fun part... The radiator! Here, there are a LOT of ways to do it. If you don’t mind hanging something off the top or side of your case, you can throw a dual 120mm rad on it (If you got the cash, a pa120.2). If you want to keep things compact, then you'll probably want to hang it off the back fan. Just mount a 120mm (or 160mm) there, with the tubes running through holes in the MB tray. Again, if you have the cash put a PA 120.1 or PA 160 here. If you don’t, it just depends on the noise level you want....
A few people has also put 80MM's up front. It helps, but isnt necessary.
On last thing... In a X-Qpack, COOLSLEVES ARE REQUIRED. There is just no room to not use them.
Hopes this helps.
