The inside of the enclosure is pretty simple. The drive mounts directly to a sheet of aluminum, which helps dissipate the heat.
There is a power bus, an SATA bus and an IDE bus.
Here's a cool little jumper, SATA interface and power in the same plug. I would recommend connect this to the drive before mounting. It's a tight fit and probably would be a little trouble connecting after the drive is screwed in.
There are two types of screws included, phillips head and box head. The phillips head screws are for mounting the drive in the enclosure. I never noticed that there are four screw holes in the bottom of the drive...I guess all of them have those holes, though.
The drive is held firmly in place by four screws.
Connect the jumper to the power and SATA buses. Carefully slide the mounted drive into the case.
Use four box head screws and the included screwdriver to close the case. Be sure to put the screwdriver somewhere that it won't get lost or misplaced.
And installation is finished.
Let's try it out.
