Originally I wanted to use a PATA to SATA adapter, but that didn't work out. There were a couple reasons I guess. I know the Raptor has a reputation for getting a littlw warm (though I haven't really seen that). Also I toyed with the idea of RAID0 striping 2 Raptors, but that didn't work out (could only get one Raptor on the cheap). Also, once I wired everything, the lower cage was easier to remove. Since the PATA drive will be replaced, it was a matter of convenience to put it in the lower cage. I have rounded IDE cables, but all are "standard" length (16-18"). In fact, about half are short (6") mostly for my optical drives. This was more than enough cable to rout through the "forward hatch" of the P180 and to the motherboard connectors. I guess it'll depend on the board layout.
