Now Icydock is offering a new hot swap module of the same proportions called the MB674SPF-B which is completely tool free. Just open up one of the four bays, slide a SATA hard drive in and close the door. The hard drive automatically engages with SATA data and power connectors, no screws required!
The ICYDock MB674SPF-B is a seriously convenient Serial ATA hard drive backplane module, it retails for about $120 USD ($100 here ). It does not come with hard drives.
