It's actually still boxed up and unused. I bought two of these on the cheap a little over a year ago to upgrade my current system, but only installed one drive and still had this one laying around.
Seagate Barracuda Ultra ATA/100 7200 rpm 120 GB
I have a 750 GB WD SATA drive for the new PC already and thought this one would be just fine for the OS and use the big drive for everything else.
