Ground straps are a good suggestion, but something I have never used in my entire IT career.
It's easy! If I can do it, anyone (well, almost anyone) can do it. We'll help you out... Here's one I built for myself last spring and I've been tweaking it ever since... I build 4-6 computers a month for family, friends and folks at church and work... I only charge what the hardware and software cost and I never add any $ for labor...
I have dual booted operating systems but I never liked it so now I use VM's (VirtualBox) and I have about a dozen virtual machines, each a different OS that I test on. It's my job and my hobby....
Does it all run pretty well? I'd like to have Windows 8.1, Hackintosh, and Linux Mint.
