KINGWIN KF-3001-BK SATA Internal Hot Swap Rack 3 Bays w/ Fan

Pros: Works just as you would expect.

Cons: Installation is a major hassle due to a major design flaw in this model.

Other Thoughts: I considered removing 2 stars from the design flaw. Like the other reviewer I also own the 4x3. I purchased 2 of these because I wanted to go from 4 hot swap bays to 6. But they are not identical in design. On the plus side, these units have larger fans. The 4x3 has aluminum sides, these appear to be hard black plastic making them much harder to slide in.

But the major issues is that the rear panel appears to be designed and mounted upside down. What this means is that the power and data connectors are flush against the motherboard rather than away from it and easily accessible. So, if anything sticks u from the motherboard like RAM or heat sinks, you are going to have trouble accessing the connectors. A 15 minute job took an hour..

This would probably be easier if installed when building the system but adding them in was a major hassle. Their other model does not put the connectors next to the motherboard.

Other than installation, they work fine and the drives slide in and out easy as you should expect.

Pros: Excellent design when it comes to swapping drives, no trays or anything else needed, just slide a drive in and click it. The LED lights look good and work really well displaying activity. This cage is by far the best looking one I've seen.

Cons: My unit has two fans and both died within a few months, oh well it still works since my case has pretty good airflow.

Other Thoughts: I own the 4x3 instead of this 3x2 but they are essentially the same.
