Opening the Case:
Remove the screws on the back of the case then pull back, and push up.
Attaching the Case Feet:
The case feet are attached by removing the sticker on the foot, then placing it in the appropriate place on the bottom of the case.
Installing Drives into Drive Bays:
To mount a drive into one of the 5.25" bays, first reach inside the drive cage and push the 5.25" faceplate out from the front of the case, keeping in mind the sharp edges of the case. Then slide the drive in from the front of the case until it is flush with the front bezel. Screw in both sides of the device.
To mount the floppy drive follow same procedure as a 5.25" device.
NOTE: the A500 case doesn't have a removable drive cage.
Attaching the Front Case Fan:
First, remove the motherboard panel. (NOTE: Instruction for removing motherboard panel are below.) Then press down and out on the top center part of the casing for the secondary case fan. Let the logo/brand label of the case fan facing outside to suck hot air out of the case in the front. Firmly place secondary fan in casing until it snaps into place.
Mounting a Motherboard into the Case:
This case comes with a removable motherboard panel for easy installation and matience. To remove the motherboard panel look on the back of the case below the power supply. There will be a little arrow pointing up. Press upward on the motherboard panel which is just to the left of that. Also press up in the top left corner, then pull out.
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. First, line up motherboard to corresponding holes on motherboard base.
2. Mount motherboard by using appropriate screws.
Detaching Front Bezel:
To detach the front bezel pull outward on all 6 tabs right on the inside of the bezel where the plastic touches the metal. 2 on the top, left, and right.
Attach the power supply cable. Most motherboards have a plug for an optional exhaust fan. 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, ect.)
There are several wires attached to the front bezel that power speakers, indicator lights, and switches. 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 it's location on the board.
The ATX power supply may not operate unless a working motherboard, processor, memory, video card, and at least one drive are plugged in. Some power supplies are designed not to operate unless they have a minimum load on them. If your system does not power up, it may not suggest a defective power supply, but indicate a problem somewhere else.
NOTE: Coarse-thread screws are normally used for mounting hard drives. Fine-thread screws are normally used for floppy drives and CD-ROM drives. Some cases use fine and some use coarse-thread screws for motherboards. Be sure to use appropriate screws to ensure proper installation with minimum damage.
