Explain how and why you set it up as you did: I built this PC in November 2010. Reason I went, at that time, with the highest possible specs was to be sure It would last 5 years without upgrading the internal hardware (so far, only changed the keyboard and mouse, purely for comfort reasons). It's a multi-tasking workhorse that is going so well, I'm still running it on it's first Windows 7 installation.
The computer's primary purpose(s): Gaming, Entertainment, Work, RDP sessions on my server, everything really...
