Yes, I did build the PC I'm currently using. Building your own computer gets you much better parts at a much lower price. I don't ever want to buy a pre-built. Plus, building a computer is a lot of fun.
I wish. I'm not very familiar with building computers, but all my skype buddies build computers all the time. If I'm correct, building a computer is far less expensive, and more often than not far more powerful?
This computer is about a year, maybe a year and a half old. We had the Graphics Card upgraded, but it's still just average. It can run Skyrim pretty well. I'll give this computer a year or so and then I'll go and custom build one myself.
