I need a new external hard drive, and I really like the G-drive cases. However, they don't sell just the enclosures. So I'm thinking about picking up the smallest one I can find, either a G-Drive or G-Drive Mini, I haven't decided yet (probably the Mini though), and then at some point replacing the drive myself with a larger capacity one. It looks that I can get an 80GB G-Drive or a 40GB G-Drive mini for about $100. Then, if I got the full-size one, I could put 400GB in there for $100, or if I got the mini I could do 160GB for roughly the same amount. Which either way would be a heck of a lot cheaper than buying it right from G-Drive. My question is: what type of interface is on the inside of those cases? I can't determine if it's PATA or SATA. Has anyone ever replaced their G-Drive before? I presume it just has a few screws, like any other hard drive enclosure. I would appreciate any insight, or recommendations for cases that look like the G-Drive and match their build quality.
