Hi everyone, I've been a PC user most of my life, planning to make the switch to Macs. I think the new 2011 Mac Minis are a good compromise of price and performance. I've built several PCs from the ground up, so I know all about upgrading them. I understand that the Mac Minis do no have the same flexibility as PCs when it comes to upgrading. What components can be upgraded? From what I've read, only the RAM and hard drives can be user upgraded, correct? What are my options in terms of hard drive upgrades? Thanks.
