First - all the parts came perfect, and during the build I ran into no problems, which i was surprised because this was my first build and I was expecting problems. Computer booted up with no errors and everything was fine.
Second - I used this computer for editing, browsing and gaming. Games played so far are Planetside 2, Warface and Gta 5, which two I got 40-60 fps on high settings, except for Planetside 2 - which I had to lower settings, due to the fact that Planetside 2 is a CPU intense game and my CPU isn't the greatest.
Last - The computer is very silent and cool, even under load, it stays cool(even with stock cooler, which is what I'm using) and the monitor and keyboard/mouse are very good. Also the case looks nice with the red led fan at the front.
ALSO - the reason windows isn't in my build is because I got Windows 8.1 Industry Pro for free from Dreamspark, if ur a student u can sign up and get some expensive stuff free.
Problems: The only problem I ran into was installing windows, but that was my flash drives fault.
