Give me the design you want and I shall do it I will put it on my server for as long as you want You could invest in a domain name and some hosting in the future though !
If you want to do gaming, don't get an APU. Read reviews and benchmarks on hardware you aren't too sure about. If you are building an AMD rig, get this:
Newegg.com - AMD FX-8150 Zambezi 3.6GHz Socket AM3+ 125W Eight-Core Desktop Processor FD8150FRGUBOX
You should be fine to do that. I would recommend disconnecting your current hard drive to make sure you don't accidently wipe your data and also knowing windows it will probably screw your boot loader.
I know man, I took a massive break to get stuff sorted in real life I fancied a change so I thought the best way to go around that would to stop gaming for a while! Life is perfect man, been with the other half nearly 8 months now so I can't ask for anything more Hows life your end?
