Links to new PC system

This mostly so I can see everything that's going into the system. Some of this I've never heard of before. Naturally. But the idea is to get a great gaming rig that will last me awhile, yet not the newest tech either since money is a concern. I didn't want to sink another $3000 into yet another PC right now. Give me 5 years out of this one.....please.

Video Cards - Two of these to take advantage of the SLI technology for 1gb video RAM (I think thats what it's called)

You gotta have a cool case. There were alot to choose from, but when going over these with the guys, we picked a full tower that had great user reviews. So maybe not as flashy as some, but I think it's pretty. :)

Windows 7 Home Premium 64-bit
4gb RAM (I can always add more later if needed, so this was fine for what I do with the PC)
