I have a PowerMac G5 (dual 2Ghz) with a very outdated IDE-based superdrive that I'd like to replace with this BDXL burner, which is SATA based. I've already added two additional SATA hard drives (total of 4 internal) via a PCI-X based 2-port SATA controller card. In order to install that BDXL drive, would I just need an additional SATA card to connect it to (or remove one hard drive)? Or, would I have to get some sort of IDE to SATA adapter to attach to the IDE cable that's currently connected to the drive? And after all that's said and done, should I expect OS X 10.5.8 to support blu-ray burning in the Finder or with Toast/Disk Utility? I'd prefer to get an internal drive rather than external, but would appreciate any insight into whether or not I'll have any problems getting this to work. I found this adapter, which looks like it would do the job. Any reason why it wouldn't work? Thanks!
