very good start.
a few things tho.
1. you really need to seal those barbs. They will leak. If you didnt use plumbers tape, then i suggest you get some. But sometime plumbers tape wont hold out.
So i really really really recomend you getting some silicon and sealing up those barbs. If you dont want to seal them, then get some metal barbs. I recomend the D-tek G1/4 barbs which can be bought at shoppts.com
If you get the EK barbs, you'll need to double up on the rubber sealers. Swiftech seems to have depth the barb area, so it wont do a perfect seal unless you double up on the rubber seals.
2. what do you intend on cooling? the MCR220 is only about good for a cpu and northbridge loop. It may take a small video card, but you'd be really pushing it if you dropped in a high end card.
Also why didnt you just mount the rad off the rear? you could of gotten a MCR220-Res combo and saved yourself mounting a res by doing that if you did it off the rear.
