I'm getting close to upgrading my 2008 MBP. Since I keep it hooked to a monitor most of the time and use my iPad for most tasks that require portability, I don't really need a laptop computer, and the Mac mini looks like the best bang for the buck. My primary uses are editing photos with Aperture and Photoshop Elements, and making music with Logic, all at the hobbyist level. From what I've read, the quad-core i7 seems like a worthwhile upgrade over the i5. In browsing several old threads in different forums, I saw that several people recommended getting the Mac mini Server. I'm guessing that's because of the two built-in drives rather than the OS X Server software, but what is the advantage? Is it for using one drive as a scratch drive, or for using both drives in a RAID 0 configuration? Is it anything that can't be done with an external drive? I also know that you can add a second drive to the non-Server model.
