Query: Good Idea, poor execution

My backup drive needs to be on all the time, so forced cooling is required. This seemed like a good enclosure to use. However, I will be replacing the 2 that I bought very soon.1) The fan is EXTREMELY cheap and soon became noisy with a rattling sound. Unacceptable.2) They cleverly circulate the air around both sides of the drive for cooling, but the placement of the rear vent prevents you from stacking enclosures, so you would waste a ton of space if you had more than one. It would have been very easy to place the vent so you could stack them.3) The power switch is on the rear, instead of the front where you can easily access it. My drive is on a high shelf with the cables in the rear and it is very hard to find the switch when necessary.Sorry - this is a product FAIL.
