I'm starting to gather parts for my upgrade in april, and am starting with the case. I'm settled with the midsized towers because of ease of transport to and from LANs, and want to go with a water cooling system. I've seen a few cases at compUSA that were water cooled (albeit really damned expensive), but am a little weary at installing a water system myself. how hard is it to install a watercooling system with 2 blocks? (one block for the processor and one for the vid card). also, what are some good (yet not outrageously expensive) cases that come watercooled?
