Your computer tower, if it's anything like mine is warm and dark behind. Do you have other pets? I say put a rat on the middle of the floor of each room (who cares about stench when your snake is missing?) and try that. Have you seen those videos where cats/ ferrets get into dresser drawers and pop in and out? Check dresser under all clothes. You can also keep the lights off or dimmed as often as possible in an effort to comfort him. Do you have old purses in your closet? If also check the room where his cage is a few more times because if it has a good enough hiding spot for him, he may have just stayed there
I'm having too much fun with trying to think of places for a snake to hide.
