omg it's huge
but just a few things
first of all the radiator should not be vertical
heat goes upwards, and now the lower part warms the higher parts.. not very efficient...
further the waterpump is all the way down the case, this means it should pomp lots of water upwards (against gravity) therefore you need a much more heavy pump
the power and reset buttens stick out a little bit. that realy sucks i can tell you, one bad move and you can reboot
and last but not least it's kinda sad the use only a XP2100 in it.. i have myself a 2400 in my workstation and to get a sample of a barton XP3000 won't be a problem since AMD is very genirous (orso) towards such projects
