I spent several hours last night getting the new ( used ) computer formatted and then reinstalling the OS, drivers, and other software. This morning my computer room looked like a real mess with computer parts everywhere. Today I moved things around and cleaned up a bit. It will stay this way until I get rid on the computer that I got yesterday.
I have both computers right next to each other on the floor and the monitors on my desk. This way when I show it to people they can try it out before deciding on whether or not they want it.
