The G5 uses serial ATA HDs (SATA) and says it supports two of them.<br><br>If I want to buy a second one from a third party dealer do I need the cables too, or are they already supplied in the G5 tower for the second drive (from the tech specs it kinda sounds like they are). Its much cheaper to buy a 'bare' drive from someplace like this but it comes with nothing but the drive. I've never installed a HD into a tower so any info would be helpful.<br><br>Thanks!<br><br>
