Mark, your question is legitimate and we try not to "pounce" on folks who want to do things differently unless safety is involved.
Scroll down in this category and you will see lots of air conditioner related advice. The under bed thing didn't work as well as it could have. The under bench unit worked better but needed a lot of intake air space and a small fan. Have fun with it.
Someone may have the time to point you to the more complete threads.
