I'm getting an 24" Alu-iMac (3.06 GHz) by the end of the week. I have an old 160 GB Seagate Barracuda HD from my former cpu that I want to use for music, videos, etc. I think it runs 7200 rpm, I'm not sure about other specs, but I will soon. Any generally good enclosures (companies/models) out there that are pretty cheap? Any type; plastic, metal, aluminum, whatever.
