Let's begin by taking a look at the main part of the Vantec enclosure. It is not quite as long as a US dollar bill, but it is slightly wider. The bulk of the body is made out of aluminum and the ends are made out of plastic. The front of the device includes LEDs which will indicate activity and power status. The sides have tracks to ensure this piece slides into the internal unit properly.
The back of the unit (above right image) is fairly plain with four connections. From left to right there is a standard SATA data connection, a SATA power connection, a mini USB connector, and an external power connector.
The main portion of the internal housing looks like an old tape drive. The front of it has a little door which covers the internal components, and to the right is a silver eject button. The sides of the housing look like a floppy drive, with three different holes to secure it to either the included 5.25" drive bay adapter or directly to a 3.5" bay in your case.
The back of the 3.5" housing includes two connectors, one for SATA data, and a mini four pin power connector. There is an included adapter to convert a typical four pin Molex connector on your power supply to plug into the mini four pin power connector.
If you prefer to install the Vantec EZ Swap EX 2.5 Inch Hard Drive Enclosure in a 5.25" bay instead of a 3.5" bay, you have to use the included plastic adapter. The 3.5" portion of the device secures to the 5.25" portion with a few screws, and then the 5.25" portion can secure to your case with more screws (or tool-less drive rails if that is what your system uses).
Vantec has included all the necessary accessories to use this device. At the top we have two USB cables; the first is for data, while the second provides power. Next we have a nice, hard bound, zippered carry case, which includes a wrist strap and two internal pouches (one for the cables and one for the drive). On the bottom row we have two different sets of screws, a SATA data cable, four pin mini to four pin Molex power cable, and a simple user's manual.
