The following advice is based on many years of experience. They are provided as a free service to our customers and visitors.

You are welcome to distribute these tips free to your friends and associates as long as it's not for commercial purposes.
Attaching the Rubber Feet:
Find the circular indentions for the feet on the bottom of the case (Photo 1). Align the tabs on the back of the feet with the holes and press the feet firmly into the case (Photo 2). The feet should twist freely when installed completely.
Inserting Drives into Drive Bays:
Remove both side panels by unscrewing the four screws that hold them from the back (Photo 3). (When working with computers, it helps to have a magnetic tip screwdriver so your screws don't fall somewhere inaccessible when you loosen them). Press against the panel and slide it back until it is detached. Then lift the panel off and set it aside. Do not worry about which panel is which, they are interchangeable.
(When working inside computer cases, remember that many computer cases have rough-cut metal edges inside that will cut you if you are not careful. This case actually has most of its edges rounded, but somehow, I always manage to find the ones that aren't.)
You will need to remove the faceplate of any drive you wish to install first (except for the hidden drive bay). To do this, look inside the case for the clips on the back of the faceplate (Photo 4). Pull one clip gently towards the center to detach it from the case (you may need to use a flathead screwdriver to do this).
Push the faceplate out of the front end of the case (Photo 5 & 6).
Slide the drive into the bay from the front of the computer (Photo 7 & 8).
Align the screw holes and secure the screws on both sides. Tighten the screws snugly, but not too tightly (Photo 9). If you tighten them too much, they may strip whey you try to remove them again. Making a snug fit will help prevent vibration from a drive that sits loose in its bay.
To install a drive (such as a hard drive) in the hidden bay,
simply slide the drive in from the back and secure it with the mounting screws (Photo 10).
Handle the drive by the edges to ensure that you do not pass an electrostatic charge to the circuitry.
Installing the Optional Case Fan:
A case fan is optional, but helps keep the overall temperature of the case down, and so is recommended. Higher MHz coprocessors tend to generate more heat and so require better cooling mechanisms. A case fan can help with this. Many newer motherboards have connectors for several case fans, so you may place the case fan anywhere you wish. Feel free to use super glue to attach the fan to the case (but don't glue it to any circuitry!) To install a fan, first remove the left side panel. The fan mount is located at the bottom front of the case (Photo 11). Remove it by releasing the clips on the outside of the case. Find them by reaching under the color plastic front (or the "bezel"). Once the fan mount is removed, insert the case fan into the mount until it clips in (Photo 12). Return the fan mount to the case.
Installing the Motherboard:
This case has a removable motherboard tray, making it much easier to install the motherboard. To access this tray, remove the right side panel. Then remove the screw in the back that holds the motherboard mounting tray (Photo 13).
Push the tray forward and remove it from the case.
There are more mounting holes on the motherboard tray than you will need for your motherboard. To determine which holes you will use for your motherboard, align the motherboard to the holes on the mounting tray. For this motherboard, each mounting hole has a silver ring around it. For each hole that aligns, attach one of the metal spacers by inserting it lengthwise into the hole on the tray. The spacer just snaps in (Photo 14). When all are inserted, place the motherboard on the spacers and secure it to the tray with the mounting screws (Photo 15). Use a washer for each screw. The washers keep the screw head from coming against the circuitry of the motherboard.
Before you install the mounted motherboard you will need to examine the integrated I/O ports at the back to see if you need to pop the covers out of those that you will be using. For instance, the Sound Card interfaces need to be uncovered if you have installed a sound card or there is sound built into your motherboard. You can take the I/O plate off the case easily. It just snaps out (Photo 16). If you place it against the I/O ports of the back on the motherboard, it will become obvious which covers need to come out (Photo 17). Pop out the covers for the I/O ports you will be using and snap it back in place when you’re done.
Return the mounted motherboard to the case. Set the bottom of the tray in the groove at the bottom of the case, and then align the hooks at the top of the tray with the holes for them. Slide the tray backwards into place (Photo 18), making sure that all the I/O ports align properly with the I/O plate. Secure the tray with the screw at the back. Replace the right panel.
Connecting the Power Supply:
Align the backside of the power supply to the case and mount it with the mounting screws (Photo 19). Unwrapping the bundle of wires that are attached to the power supply. Find the ATX Main Power Connector (20 Pins). On this power supply, the cords from the Main Power Connector are bundled with a black mesh so it is easy to identify. Plug it into the motherboard in the socket labeled ATX power. There is a clip on the Main Power Connector and a hook on the ATX power socket, make sure these connect and that they click into place. Next, connect the power supply fan. Find the Fan Monitor Connector (3 pins) and attach it to the three-pin connector on the motherboard that reads "Power Fan."
Lastly, you will want to connect the Panel and Jumper Pins from the case to the motherboard. These control the indicator lights, power switch, reset switch, and system speaker. Refer to your motherboard manual for the proper placement of these connectors.
