That's funny that you made this thread because I have always overlooked the mini for some reason. It just never registered with me to take them seriously. Now that I've been looking into upgrading my Mid-2007 iMac, it's looking like a more viable and economical option.
Unfortunately I already ordered a 512GB SSD, the cost of that hard drive alone could of bought me a pretty good mini that would out perform my current system 3 folds. Looks like I'll be having to get an RMA when it arrives.
