Replaced the RAM (upgraded to 2X16GB) and added a second SSD. The whole time I was worried that I would mess up in some way and have a very expensive paperweight.
Let me tell you, the reboot scared the crap out of me (looking boot time, keyboard cycling through the colours, and a message about repairing the C: drive), but eventually it started back up.
And now I have a cooler machine!
Next on my upgrade adventures: adding a second hard drive to my tower (more space for pictures!!).
