Hi, actually there is plenty of room to mount a rad at the bottom of a A71 without having to cut anything and you can retain the hard drives as well. Then you just mount the PSU at the top of the case....

That would be great but I am limited to a bottom placement of PSU with my Hiper Type-R PSU with the power connector placement, but its a good point!
Another option would be to mount the PSU in the drive bays leaving the top and bottom of the A71 for 2x 120.3's

Oh.. the options!
