The latest in a new series of adaptable cases, the J3630 [black] and J3160 [beige] are 3U high, and 16″ deep, supporting up to five removable drives, a slim optical drive, and three internal drives. This gives it the largest capacity for a system its size. And with the included ultra-quiet fan, and a “silent” power supply, it is also the quietest.

This small chassis supports any microATX board and up to four full length PCI cards. There are two USB 2.0 ports on the front I/O panel. The lockable door protects drives and controls, and opens wide enough for any style removable drive. Mounting for a vertical slot-loading slim optical drive is standard, freeing up valuable space for other devices. The standard system comes with two 5.25″ bays and one 3.5″ bay, but many other combinations are possible.

To keep hard drives healthy and cool, three unique internal mounts suspend them in the path of fresh air flowing through the system. You can also add an extra 80mm fan for additional PCI cooling. Customize your system with six removable panels for additional I/O or silkscreened logos. See the mechanical overview drawing for more details.

Nearly Silent Operation

If not for the power LED, you would have to put your ear right next to this system to tell if it were on. It features an AcoustiFan™ 120mm “ultra quiet” case fan. Even at maximum speed, this amazing fan runs below a whisper at only 24.7 dBA. But, when throttled by the system board, it will cool the system inaudibly, below 10 dBA. See the Acousti Products site to read reviews and details about this unique fan. Coupled with a “silent” Seasonic power supply, rated at only 22 dBA, this system is among the quietest available. This makes it ideal for workstations, home theater, and DVR applications.

Smart Add-On Options

1) Removable Air Filter Kit: Dust build-up can reduce the effectiveness of heat sinks, clog cooling fans, and lead to failures. Protect your system from dusty environments with the RK637 filter kit.

2) Drive Bay Cooler: If your removable drive frames lack built-in fans, consider the life-extending benefits of a drive-bay cooler. The RK636 forces cool air through the bays, keeping your hard drives cool.

Drive Bay Configurations

The standard chassis is equipped with two 5.25″ bays and one 3.5″ bay. But, many other combinations are possible when “low-profile” (30mm high) 5.25″ bays are used. All configurations below include room for a vertically mounted, slot loading, slim CD/DVD drive:

A) Two 5.25″ bays, one 3.5″ bay

B) Two 5.25″ bays, one low-profile bay for removable hard drive

C) One 5.25″ bay, two low-profile bays
