Appropriate Case for W/C Kit?

Hello there, going to keep this short and sweet.

I've been looking around, got some advice from this forum and decided on a W/C solution - Swifttech H20-220.
Overclockers.co.uk

Since this is my first attempt at W/C and its to accompany my new build I'm looking for more advice on what case would be appropriate for the kit.

I want the loop to go through the processor and northbridge primarily and then later upgrade with a VGA block. So its going to be fairly space consuming. This brings the question of what case can i choose for this?

I'm curious if i can choose a "smaller" tower to fit this system, I'm fine with the Radiator fitting on the back. So far i have looked at the following

I've looked at the following;

Aspire Discovery
Casetek DaCapo
Coolermaster Stacker

Comparative to the Antec 900 and Thermaltake Armor these cases are a lot smaller. So is it feasible to Water cool with such cases?

Most of the dimensions of these cases are around;
250 x 536 x 638 (WxHxD mm)

if your willing to spend 150 on watercooling you can get a much better custon kit.
