To access the interior of the U2-UFO Aluminum Cube Computer Case requires separating the one piece "U" shaped top panel from the bottom panel. The top portion of the case does not use a three panel configuration seen on most cube cases currently on the market. The U2-UFO receives its name by using a chassis design typically seen on most desktop cases. There are a total of 14 thumbscrews (7 on each side) that must be removed in order to access the case interior. I still find this type of set-up a little tedious as previously noted with my original U2-UFO review and would have preferred removable side panels. The one piece "U" shaped top panel does not use any clips or hooks to keep it in place, rather it sits comfortably on top of the case chassis and is held in place by the thumbscrews.

Inside the case is an adequate amount of room to install a complete computer system. Chassis construction continues to be extremely strong and should be very accommodating when mounting system components inside this case. There are two areas which make up the interior, where the left side is designated as the motherboard location and the right side for the internal and external drive installation. There are a total of nine 3.5" drive bays available which makes this case suitable for multiple HD or RAID array configurations. Three 80mm fan mounts are available to keep the hard drives cooled and operating temperatures to a minimum. Like the external 5.25" drive bay cage and motherboard tray, the internal 3.5" drive is also removable and is secured using six thumbscrews.
