RAM memory and Blu Ray drive

A few weeks or so ago I installed the new DDR 3 RAM that I had bought from Newegg.ca. It's pretty nice now with the extra memory. And if I want to do some video editing and encoding I will have that extra RAM.
I have also bought a Blu Ray drive. I bought it to backup my files so I can reinstall windows for maintenance purposes. I haven't installed it yet since I don't have a SATA cable and also I am busy with other things. Hopefully I can get it installed this weekend.
