A unit which mounts in 3 x 5.25" server/desktop drive bays providing 4 x 3.5" hot swap drive bays providing tooless insertion of upto 4 x 3.5" SATA HDDs. The unit has its own cooling fan and connectors as pictured.

Basically allows 4 SATA disks to be fitted in front of server/desktop case allowing for easy removal/replacement/expansion.

Can additionally provide SATA cables if required. I have some SATA-SATA, SATA-sff8087.

This was recently removed from my home server and works perfectly.
