Installed a new 500gb SSD in the computer. Transferred my Steam library to it, which was totally painless.
My main SSD is only 160gb, which after the space windows 7 was taking up didn't leave much room for games. Which was fine since I've pretty much just played Skyrim since 2011 (in the tiny time I actually have to play games), but its time to branch out.
I was going to build a new PC, since mine is 2 years old, but it turns out its still pretty kick ass.
