Pulling the side panels off we can get a look inside the Three Hundred Two. The Interior is not painted; it is a budget minded case. The layout is where the more noticeable changes from the original Three Hundred design are. The hard drive cage now runs side to side, rather than front to back, and are now tool-less. The 5.25″ bays are tool-less. The motherboard tray has a massive CPU cutout, and now sports wire routing holes. The accessories come packed in a baggy and wire tied to the hard drive cage.
There is space for six 3.5″ hard drives. The drives mount to the cage with drive rails. Since Antec went with rails rather than trays there is no option of mounting 2.5″ drive in the drive cage.
There are two mounting points for 2.5″ drives. First is on the floor of the case between the power supply and the main hard drive cage. The second is up on the motherboard tray near the CPU cut out.
Under the PSU is the side accessible dust filter. This can be removed from the side without removing the side panel.
Above that are the expansion slot covers. From the back of the case to the hard drive cage you have room for video cards up to 12.5″ long.
In the top rear are the exhaust fans. The 120mm fan is powered with a standard 3 pin connector. The 140mm on the other hand is powered with 4 pin molex connector.
On the right side of the case there isn’t a lot behind the motherboard tray. There are tabs for tying down the wires.
Looking closer we can see the second 2.5″ drive mount area. With a full size ATX board installed the two mounting screws closest to the CPU cutout will be covered by the board. So to remove the drive later the board would need to be removed.
Pulling the front bezel off we can see the mounts for two user installed 120mm fans.
The I/O ports are attached to the case frame, so when the bezel is pulled off there are no wires mess with.
The intake dust filter on the inside of the front bezel is removable. The screen snaps into place; to remove it for cleaning the bezel has to be removed.
