I ran into an issue while installing. It said "An error occurred while installing OS X" and then froze. Afterwards, I got a bouncing question mark. Booting into internet recovery several times, and it couldn't find my HDD.
I finally assumed that it had probably fried my HDD somehow, so I powered off and ordered an SSD online since I was looking to upgrade anyway. I unplugged it from the wall and turned it on and it suddenly found the Mavericks installer again.
I didn't have this problem, but removing external monitors during the install screwed up the installers view, I could tell it was still running, but not refreshing. Eventually it finished and view started working again.

It seems to be working now.
