Hi. Just a quick question. Have purchased a mac mini. Latest model with leopard, I got the combo drive model. Am comfortable with taking it apart just want to know if I can swap out the drive for any slot loading one such as an Optiarc. I have a superdrive form am old broken macbook but it is slimmer than the one fitted into the mini. It doesn't line up properly in the machine. Just want to know before I shell out on a new drive. Thanks for any. Oh!! Also can I just pop a quicker merom in the machine or maybe even a penryn?
