I have acquired a desk that allows a monitor to be mounted at a good viewing angle but sort of inside the desktop. It would sure clear my line of sight from my desk if I could mount my 20" imac inside this desk top. There is plenty of clearance underneath for air circulation and for the stand (which apparently cannot be removed) but I AM concerned about overheating. If all other elements (ventilation etc) are good, is there any reason that the angle itself will negatively affect the imac? As always, thanks for the help.
