FlexCage MB973SP-2B

Introducing the FlexCage MB973SP-2B, a 3-in-2 Tray-less SATA 6Gbps HDD Cage for 3.5” SATA hard drives. The FlexCage brings enthusiast preferred features such as: plug & play Tray-less design, replaceable 80mm cooling fan, 3 speed fan control with Smart Cooling Technology, integrated USB 3.0 hub, and full control of your drive with individual childproof power buttons. It is designed to be used in consumer and enthusiast systems such as, gaming / media computer cases, and home servers that hot swap frequently.
Space Saving & Tray-less Design
The MB973SP-2B is designed to maximize space use by allowing up to 3 x 3.5” SATA 6Gbps hard drives, while only consuming two external 5.25” bays. The FlexCage also only requires two 4-pin power ports (or two 15-pin power ports with included 4 pin to 15 pin adapter cables), to power up to three 3.5” hard drives. The FlexCage is equipped with our renowned tray-less technology – no screws or tools are necessary to insert or eject the drives, making hot swapping a completely hassle free experience.

Intelligent Cooling

The FlexCage MB973SP-2B uses a large 80mm rear cooling fan to pull cool air from the front ventilation slots, over the drives, and exhaust the warm air out through the rear ventilation slots.
The FlexCage also allows the user to choose the speed of the fan, or to select “auto” so that the fan adjusts its speed using our Smart Cooling Technology. Our auto function determines the temperature of your drives, and changes its RPM accordingly. This results in decreased power consumption, an increased lifespan for your fan, and unnecessary excess noise. Along with the auto function, the user can also choose a high setting, best used for intense applications such as home server use, or a low setting, best used with lighter work loads such as hourly back ups or audio recording / editing.
The included 80mm cooling fan is easily replaceable and maintainable, as it is compatible with most aftermarket cooling fans of the same size. To expand the range of compatible fans, both 2 and 3 pin standard fan power ports are available and can be easily accessed. To support the cooling system in place, the FlexCage body is built using full aluminum to help dissipate heat even further.
Built for Enthusiasts
Keeping up with the latest external storage technology, the MB973SP-2B has dual USB 3.0 SuperSpeed hubs to easily connect the latest external storage peripherals, especially for systems that do not have top / front USB 3.0 port access.
The MB973SP-2B features the Active Power Technology+ power system, giving you full control of your hard drive environment. To power up your hard drive, the front of the device includes childproof power buttons for each drive which require the button to be pressed slightly deeper than normal to ensure that a drive is not accidentally turned off by bumping into or rubbing against it. These power buttons double as an LED indicator showing drive power and activity. When one drive is turned on, the 80mm cooling fan will also turn on to start cooling your hard drive.

The FlexCage incorporates our Flex Fit Design, which accommodates to different tab lengths when installing to a server or tower computer case. This reduces the build time or fit issues seen with other cages.

Similarly, each drive door has a multi-locking latch mechanism in order to prevent a door from being opened easily. Each door panel is built with a solid aluminum panel, making it an ideal solution for systems that need a reliable and durable door design. Lastly, to ensure a peace of mind, the FlexCage is backed with our 3 year warranty, equivalent to a hard drive’s warranty.
