After using a Mac since the start of high-school, I finally built a PC for gaming and daily use. I generally play games like Civ V and Skyrim, but I might expand to more games now that I have a proper rig. Building it was really as easy as people have described, plug and play for the most part, although the HDD gave me some trouble going into the case. All in all, I'm quite happy how this turned out, especially the keyboard (not of my own design, got it from this post.
