Case for watercooling

[utherpendragon]

Looking at the antec p180. Nice looker and the top vent looks like a possible spot to feed tubing through discretly. Are there any better cases for the money though? Looking at using a 120.3 radiator on it so ideas on mounting spots would be greatly appreciated as well.

Thinking about getting the p180 and mounting the radiator on either the side or rear of the case (with a radbox). With this I could feed to tubing through the existing top vent (cutting away at the guard if there is one there). Does anybody see any obvious problems with this (first real step into watercooling).
