since the ZALMAN CNPS7700Cu needed 25mm from top of CPU bracket to bottom of PSU (On a Soket 478 setup) and i only have 10mm but the PSU hangs 17mm below the top of the case...i wish i could move the PSU up to the top gaining 17mm but it cant be done (easily that is) so i decided to go with the ZALMAN CNPS7000Cu instead but before i buy it...is there a big difference between the 7700 and the 7000? check my sig if u need details on system i will be applying it to
