Xigmatek COA-UGOCBS-U01 Universal 3 in 3 SATA HDD Hot-Swap Cage 120mm Fan with control, back panel included.

Pros: after some getting to know the product it works great and the looks it gave to my Antec Nine Hundred Twov3 is awesome.

Cons: There isn't any instructions that come with the product itself and I have two of these. My complaint is the plastic hinge on the second swap bay broke off

Other Thoughts: I wish Xigmatek made a hot swap bay that was similar to what Zalman does by installing the blue fan inside of the front bay door so that the blue lighting isn't hidden.

Pros: The overall build quality of this drive bay unit is excellent, particularly when the fact that the drive rails and their associated tracks are plastic. In addition, the 120mm fan coupled with the spacing between each drive yields fairly good airflow.

Cons: I have two of these units in my case and the outer door has a tendency to rattle on occasion. In later revisions it might make sense to incorporate linked latches on the upper corners of the outer door as opposed to a single central latch.

Other Thoughts: "Switchable high/low 12cm exhausting fan speed on the backside of cage." - I have been unable to locate the switch which controls this functionality, however, whatever mode the fan defaults to is still quite quiet.
