I actually like this idea for the most part, even though it would disqualify me
I think it may be a bit unrealistic to expect people to have all the hardware ready for install though, as it's asking a lot to buy kit for the case when there's really only a kinda slim chance of winning...
Personally while I'd use the case I don't think I'd do it justice really. I'd just be fitting a standard water cooling kit in it for the most part.
Thumbs up for the idea though, I think a lot of people could do some pretty interesting things with this case, especially if they got in to modding it to make it look as beastly as it performs.
