still, the Eclipse isnt the best case to mod to fir WC into. Not many 5 1/4 bays for bay mounted WC, and the top has the PSU which'll restrict the space for WC up top.
PC-G70, tons of space, some would say it's the ideal watercooling case (short of an MM).... can EASILY fit a 120.3 internaly, and probably another loop for gfx if needed. I've seen good setups in TJ-07's as well.
guys, he wants a case for WATER COOLING, so stop going on about how good the Eclipse is, although you can sneak a pump/res down the side, you will be HARD pressed to fit a 120.3 in there, max limit is nearer to 2x120.2, 1x120.2, and that's if you dont mind sacrificing half the drive bays to fit a 120.2 on the top, and you dont have a stupidly sized PSU.
MM's cost a fortune, fow which you can probably buy another case AND the watercooling. I'd say get a cheaper case (which is just about ANY case) and spend the money on decent WC, especialy if it's your first time.
I'd look around, and try and find some pics of WC rigs in the different cases, and compare that to what YOU want to build. That way you'll have an idea on placement, performance, and not be dissapointed.
