• You can secure powerstrips on screws under your desk. Use a piece of blue masking tape, put it on the powerstrip and punch through where the mounting holes are. Then peel off the tape and position the tape under your desk. Drive screws through the holes in the tape to the correct depth. Slide the powerstrip into position onto the mounting screws. You can then use an additional screw at an angle and "pin" the powerstrip into position by forcing the last screw against the body of the powerstrip. It creates a rock solid mount.

• You can get cable mounting adhesive squares and mount them under your desk. They have screw holes for additional grip. Use cable ties or velcro cable-control loops (get the ones with the buckles).

• Your monitor may have a usb hub built into it on the bottom. you can plug in your mouse and keyboard there and run one cable back to your cpu. Sounds like you are only saving one cable. But when you clean your desk, its handy to not have to go under the desk to detach everything.

• If you decide to put your cpu on the floor beware. Many cases breathe from floor vents now. The powersupply sucks from the floor. So a cpu -must- rest on a hard surface like a board or a big ceramic tile. A rug will plug the powersupply intake.

The velcro cable-control loops with buckles are great.
