After 2 days of downloading and a few hours of installing, poof-and I installed the RC! I clean installed it, so now I'm installing my programs and moving my files. It's great! Much better than the Beta. There are many changes, which you can watch as a video here.
Still, you can get the RC here, and the program will last until July. The system requirements are as follows:

x86:
1GHz or faster processor
1 GB of RAM
16 GB of available disk space

x64:
