Right now I use a PowerBook G4 with a 4200 RPM drive, so I could definitely benefit from the faster drive speed the Mac mini has to offer. My everyday "big" tasks consist of graphic design and digital photography. I tend to work with large files now and then, which brings me to my main question: would you suggest upgrading my Mac mini (if I get one) to a 7200 RPM drive myself? If so, is it difficult? 7200 RPM drives are pretty expensive on newegg.com, which makes me wonder if 5400 RPM is enough. Oh and I will be dealing with HD videos, but only downloading and playing them, not editing. Thanks!
