SVC has Coolermaster Aluminum 631's on clearance and a $15 MIR. (good till 07/01/2007)

This is a nice case with holes in the back (next to main PSU) for external water tubing, though it could be use with power cords for a 2nd PSU to power a pelter or for the power cord of a non-12V water pump.

Here are the links and prices:
*note these cases are without a PSU and the price listed is before rebate

There will be about $15 shipping (in US w/ USP ground) so the before-rebate price is close to actual total final cost after shipping w/rebate included.

So the rebate about gives you free shipping, unless you live in the area and can do "in-store" pick-up.

The silver one is $109.99 at zipzoomfly.com with free shipping
