danger den mc-tdx water block, black ice Xtreme II rad (2, 120mm fans), D5 pump. and fillport. i was also thinking that i might use 2 black ice micro II (2, 80mm fans) rad's instead, but thats only if i can't fit the xtreme rad. i've always used distiled water and it works freat so i think ill stick with that, i just wanted to try something new. by the way this setup will cool a phenom II 955, a hd4850(maybe 2 of them). ONE more question, is it worth it to water cool the hard drive?
