Built it because my laptop just wasn't cutting it anymore.
Works very well overall. I just wish I would have picked a modular power supply. The fan that comes with the water cooler is very loud (I replaced it recently and saw a huge reduction in noise) and the pump is also loud (but tolerable). I also replaced the stock top fan with 2 corsair af120s. (which are great).
The BIGGEST PROBLEM with this build, was that the hole in to access the back of the motherboard to attach CPU coolers wasn't quite in the right spot. I had to cut away a bit of it to make room.
The monitor listed here is the more modern version of the one I actually have (same price and specs though). (same with the keyboard)
First picture shows it with only 1/2 the ram, one HDD, and no graphics card installed... (the rest are normal) Yes my ability to manage cables is severely lacking...
