You do not want the backside of your desk and computer facing the door. The cords running across the floor are dangerous. Someone will trip on them for sure. Consider putting the desk underneath the window? Or as in #1, but look at the cord running to the plug under the window.

I like the first option, the second one looks kind of messy and un organized. Maybe of you up the desk in front of the window instead :)

The second option is a dangerous one, with cords across the floor.

Don't do it.
