I built my first computer when I was 14. I am now 18, this is my current build, first put together on December 28th 2012. It cost me just shy of £800.
I use the computer for gaming, web browsing and video/image editing.
I just recently got around to overclocking my CPU to 4.0GHz. I can get 4.2GHz but in my opinion, low temperatures > very high clock speeds.
The only problem I have had so far is that the memory was underclocked for some reason, so I had to manually adjust it. I also had a bit of trouble updating to the latest AMD 13.1 drivers (thanks to TkrZ) for helping me fix it.
Upgrades in mind: - more case fans - high end thermal paste
I hope you appreciate my effort on cable management. I do like things to be neat. And I don't like LEDs or unnecessary rice in general
