If you were reading carefully, you'd see that that is not an option. The computers at work are not mine, and thus I could likely lose my job if I started modifying them.

Hey, now! Don't be pissy. You never said how much control you had over your PC at work. There are any number of jobs I've had where I could do exactly what I described.

Honestly, my assumption was that if your employer was going to allow you to play video games at work, what difference would adding a card to their computer make?

In addition, you could get an RCA->USB adapter and not have to ``modify'' their computer at all, other than, likely, adding drivers.
