This easy to install printed circuit board (PCB) allows owners of Zalman's GS1000 gaming case to increase the number of hot-swap hard drive bays from 3 to 6.

Zalman ZM-HS100
On the front side of the board, there are three SATA/power ports which directly connect to up to three hard drives. Then on the other side, the HS100 has three SATA connectors which need to be connected to your motherboard/RAID card as you would normally connect any hard drives, plus two standard Molex 4-pin power sockets which are supplied from your PSU.
In its purest sense, "hot-swap" means that hard drives can be connected and removed without having to power down your PC. Please check to ensure that hot-swap is supported on your motherboard/RAID card and operating system before attempting this. If hot-swap is not supported by your hardware or operating system, the ZM-HS100 can still offer the convenience of being able to easily install and remove hard drives with the PC powered down, without having to open the PC case and plug/unplug SATA power and data cables.
