Just like the title queries. I have a 5.25 and a 3.5 size drive that I would like to take from my old PC and use with my new iMac. I could of course fashion something myself, but ideally I would be able to buy something that fits the need and save myself some time. After all ease of use was the main selling point of OS X. EDIT: I should note that this is not for a USB/FW Hard Drive, but rather a memory card reader that I find very useful. I'm interested in possibly getting a USB/FW enclosure, but I know such things already exist.
