I found a 160 gig internal hard drive at my circuit city for $30 (after MIR). I asked HP tec support if my PC supported a 2nd hard drive. They said I needed another Hard Drive "cage." They even supplied me with a link to one that HP sells. I am wondering if you can simply buy one at like Newegg or elsewhere for cheaper prices. The cage they showed me was a "Hdw Kit for 2nd HDD Mojave Gobi Chas" I am just wonder if there is a cheaper route to go with this. Thanks
