Planning on attaching 4 brackets like this under my desk to create a hanging 'dock' for my (closed) 17" macbook pro when it's hooked up to my new display and keyboard. Anyone know if heat will be an issue? The brackets I hope to find at Home Depot will leave about half an inch between the MBP lid and the bottom of the desk for air flow (about 1.5" off the bottom of the desk). I'm going to dip the receiving ends of the brackets in rubberizing handle liquid to improve grip and avoid any scratches. Any better ideas for creating a dock like this?
