Lol, only 320GB?
I had to cut down somewhere to keep it under $1000 initially. Plus, I have a 1.5 TB hard drive on my desktop PC, I use just a little under 200 GB (196 GB), so more than that would be a waste.
I have over $300 to spend so far though, if I really wanted, I could get something like this:

EDIT: Plus, I'm not transferring everything from my desktop PC onto the M11x, I'm going to exclude my ISO folder (containing a bunch of operating systems, all legal), so that's about 50 GB saved.
If I ever run out of space (very unlikely, 320 GB is quite a lot for me), I'll probably just upgrade to a 500 GB drive.
