Opening the Case
Take out the two screws holding the top of the case on. The top panel will then slide off.
Installing Drives into the Drive Bays
To remove the drive cages, remove the four screws holding it in from the top, and lift it out. Note that there are two cages, which come out together, and a third that is revealed and needs a screw taken out to be removed. The 3½-inch cage (internal) that is connected to the 5¼-inch cage removes by taking off the screw holding it on. The third cage is an external 3½-inch cage that will come off by removing the screw holding it to the case. Another 3½-inch (internal) is located behind the main c ages, and is mounted to the center rail, it comes off by removing the two screws.
The internal 3½-inch cages are intended for holding hard drives by using m3 thread screws to attach the drive to the cage. The 5¼-inch cage holds CD-ROM drives and other similar sized devices (5¼-inch), to install remove the bay cover and mount the drive with m3 thread screws, make sure that the front of the drive will be flush with the front of the case once you have replaced the drive cage. Note that it is only necessary to attach screws to one side of the cage to secure the drive. For the external 3½-inch cage remove the screws holding the bay cover and mount a floppy drive with m3 screws, make sure that the front of the drive will be flush with the front of the case once you have replaced the drive cage.
To replace the cages, first put in the external 3½-inch cage and screw it in. Next put in the combination 3½-inch cage (internal) and 5¼-inch cage in, and attach the four screws to secure it. The separate 3½-inch cage reattaches to the center rail.
Mounting a Motherboard into the Case
The motherboard you will put into this case will comply with one of several industry standards that involve the location of mounting holes and integrated components, and the type of power supply used. This case has been designed to be compatible with the AT, ATX, and Micro ATX standards. The type of motherboard that will be used most commonly with this case is an ATX motherboard, so that example will be used. To correctly mount the motherboard into the case, do the following:
1. Remove the four screws holding the motherboard tray, and lift it out.
2. Orient the motherboard to the tray so that the integrated connectors are facing the back of the tray. Make note of the mounting holes on the motherboard, and which holes on the case they line up with.
3. Screw the brass spacers into the mounting holes on the tray, and use the nonmetal washers to space the motherboard from the brass spacers. Attach the motherboard with 6-32 thread screws to the brass spacers.
4. To attach the ATX shield snap it into place in the back of the case.
5. Place the motherboard tray (with attached motherboard) into the case, lining up the holes in the tray with the screw holes in the case, and the ports in the back with the holes in the ATX shield.
6. Reattach the four screws holding the motherboard tray to the case.
7. Refer to your motherboard manual to attach the CPU, RAM, etc.
Mount the power supply in its slot next to the motherboard. Attach the power supply cable to the motherboard. There are two types of plugs for the drives installed into the drive bays. The smaller one is used for the floppy drive. The larger one is used for all other types of drives (hard drive, CDROM, etc.). Connect the larger type power connectors to the two case fans that were included.
WARNING: The power supply may not operate unless the motherboard and at least one drive are plugged in. Some power supplies are designed not to operate unless they have a minimum load on them.
There are several wires attached to the front bezel that power indicator lights and switches (power, reset system and power). The wire connectors are labeled, and have an indicator (called Pin 1) as to which way they should be plugged in. The motherboard will have pins that these wires plug into, and will also have Pin 1 indicated. Refer to your motherboard manual for a diagram of the pin arrangement and its location on the board. Attach all other necessary connectors such as IDE and SCSI cables. Put back on top and screw in the screws to secure it.
Mounting in Rackmount Cabinet
To mount directly to frame make sure the width of the case will fit between the rails. If it does not take off the handles by removing the four screws holding each mounting plate to the case. The mounting plates will reattach to the case by using the four screws that were removed. The case is now ready to mount onto the cabinet rails. To mount use four rackmount screws (two on each side) to secure the case to the rails. The screws will go through the holes on the mounting plate and the rail's corresponding holes to secure the case. It is necessary to tighten all four screws completely. Some rackmount cabinets have other rails that will secure the case along the side. To use these rails put rackmount screws through the rail, and into the threaded holes on the side of the case, and tighten completely. It is necessary to secure the front mounting plates to the rails; the side rails will secure the case more completely but are not necessary.
