This computer is a rebuild from my old computer. I've had the 660 Ti's for almost 2 years now, I will upgrade them eventually, but I have no issues with performance on this computer right now, so there's really no need.
The purpleish color you see in the case is from UV light bars in the computer. I manually sleeved the 24 pin and 8 pin cables from my PSU with UV reactive sleeving, but for some reason the camera picks up the actual UV light instead of the glow on the cables, so it looks a little different in pictures than in person.
The lights you see next to my monitor are ambx cyborg lights that change color based on what is displayed on the screen, and make gaming sweet and immersive and stuff (as long as it isn't bright in the room).
I overclocked my CPU and GPUs to get up to a 9180 on 3d mark (so that I could feel validated by 3d mark telling me I have a high end gaming PC), and then I clocked everything back to stock. As I said above, this computer performs 60+ FPS on my 1440 monitor on ultra for all games that I play, so no reason overclocking anything.
I named it Regulus because I googled "blue stars", and regulus sounded cool.
I use this computer for for light photoshop and adobe flash design work, as a media center for my TV (paying for cable is so last year), and a lot of gaming/frapsing/streaming.
