Hi all, Really enjoying my new MP. I bought the base model and am thinking of putting a second DVD-RW drive in. The stock one seems to be an LG GH61N. Can I put pretty much any SATA DVD-RW drive in or are there specific brands/types. Also, I have the ATI Radeon 5770 which is a bit anaemic. What options do I have other than the 5870, if any? Thanks.
