After the advice from this thread: http://forums.macrumors.com/showthread.php?t=221341 I decided on a drive. Okay, I'm looking at this, Seagate 300GB for $120 http://www.newegg.com/Product/Product.asp?Item=N82E16822148061 I assume that's a good drive, but if it's not, please let me know. Now, I need a case for it. I have no idea what to look for. I need it to be both Firewire and USB2 compatible.. I'll be using it with an Intel iMac, if that makes a difference. Help!
