Hello, 1- CPU what type of chipset used in the Mac Mini mid 2007 (Model MB139LL/A)? is it the 945GM/E or 945PM? I ask because I have a Mac Mini with 2.0 GHz and I have a 2.5GHz CPU is it possible to use it in this mac? I'm willing to try if none knows, but just check if it's not possible at all! my CPU is: Intel® Core2 Duo Processor T9300 (6M Cache, 2.50 GHz, 800 MHz FSB) Socket: PGA478 Spec Code: SLAQG I know the Mac Mini goes with 667MHz system bus, and my CPU with 800MHz but still I would love to have it if possible 2- Disks The Optical Drive does not work well, so I was thinking to change it to something better and I have 2 things in mind first connect a second disk with the help of a Hard Drive caddy Adapter second using the same updater to build an eSATA connector any ideas/suggestions to share?
