Unit arrived on time that was first good thing.The instructions were easy to follow and the unit went together fairly smooth with only one major glich.On rear panel  16 both sides were tapered,Had to make it straight. After that adjustment all went well,untill I tried to put my DVR cable unit in.Even though I measured my units before ordering I did not allow for the cable connections which stick out 2 inches,could not close doors.Had to do more cut outs in rear panels.They should have more pop out holes to accommodate those connections so the units can fit flush against the rear panel.
