So I just got my 2.26 octo (620 HD, 8 gigs ram from apple, 8 coming from OWC, 4870) and of course have to open it up and see how it is all put together. Moving up from the original 2.0 dual G5 with 4 gigs ram. (Had an 2.8 imac for a while but thats another story), so ready for another long term workhorse. So my question is: The empty optical bay had the sata/power combo cord and it plugged right into an extra drive i had. Can we put a Hd in this area? is there heat issues? I am planning on the 620HD to be the main core/apps drive; a 1TB drive for work files; and the other two bays be matching 500GB striped RAID (software based RAID) for photoshop scratch disks. I would still like to have a boot camp drive for the occasional game or whatever in windows, but would rather have a dedicated drive for that. So... would this location work?
