I bought the Antec MX-1 along with a Western Digital 500GB HD to expand the capacity of my DVR box. I had the drive installed, up and running, in less than 10 minutes. Remove a couple of screws, install the HD, connect the cables, and it was done. My DVR immediately recognized the drive, and asked me to format it. A minute later, done. I had originally given the MX-1 a 5 star review, but I had to knock a star off because its fan is no longer silent. The MX-1 is fairly quiet, but I notice that the fan seems to be getting a little louder every day. I may consider disabling it. My MX-1 also came with 2 eSATA cables. I was only expecting one, so I don't know if that was a mistake. Some enclosures don't even give you a cable. All in all, I'm satisfied.
