The following advice is based on many years of experience. They are provided as a free service to our customers and visitors. However, Directron.com is not responsible for any damage as a result of following any of these advice. You are welcome to distribute these tips free to your friends and associates as long as it's not for commercial purposes.
Removing the Side Panels:
To remove the side panels, four screws must be removed. These screws are located in the rear of the case. There are two screws for each of the side panels. After removing the screws, the panels are removed by sliding them toward the back of the case and then lifting it out of the case.
Installing a Power Supply:
If the power supply did not come preinstalled, you will need to install an ATX power supply. Install the power supply in the top back of the case. There are metal tabs that will hold it in place. There are four holes on the power supply that will line up with four holes on the case. If the holes do not line up, the power supply is probably upside down. Secure the power supply by attaching it to the case with screws. Make sure to purchase a power supply with enough power to meet the demands of your computer.
Installing Drives into the Drive Bays:
The first step is to remove the plastic covers in the bezel. The next step is to slide the drive in from the front of the case. Make sure the drive is flush with the front of the case. Secure the drive to the case by attaching screws. Both side panels need to be removed to be able to reach both sides of the drive. The holes in the side of the drive cage should match up with the holes in the drive you are trying to install. Use the screws included with the case to attach the drive to the cage. Repeat this process for installing any other 5.25” or 3.5” drives.
Installing a Motherboard:
This case has been designed to be compatible with the ATX and the Micro ATX standards. To install the motherboard into the case do the following. First, remove any obstacles that may get in the way, wires or drives. Next, position the motherboard so that the ports are facing the back the case. Make sure to line up the ports with the holes that are in the case. You may need to remove the punched metal that covers some of the ports. The next step is to line up the motherboard with the standard metal standoffs. The motherboard then attaches to these standoffs. Use the included screws to mount the board to the case. You can also use screw in metal standoffs for any other mounting points on your particular motherboard.
Based on the motherboard you purchased, The CPU will come in the socket or slot configuration. To install a socket chip you must raise the lever besides the socket. Insert the chip into the socket, a corner on the chip should match a corner on the socket. Finish by pressing the lever back down. A slot CPU will have retention mechanism that needs to be installed on the motherboard. Once installed, install the CPU by pressing into the slot. Make sure to install a heat sink with some form of thermal interface, such as thermal grease. Running the CPU without a heat sink can damage the chip.
Ram is installed by pressing back the tabs at end of the slot. You have to line up the recesses on the ram to the bumps in the slot. The ram will have to be pressed very firmly in order for it to be properly installed. The tabs should move into place upon installation.
Installing Video, Sound, and other cards:
A video card will be installed in either the AGP or a PCI slot. If you have an AGP card it will go in the highest brown slot. If you have a PCI card, it will go in the highest white PCI slot. Line the card up with the slot and press it in firmly. Secure it to the computer with a screw. Install all other cards, such as a sound card, in the same manner as the video card.
Attaching the Cables:
Attach the power supply cable that comes from the power supply to the connector on the motherboard. To power the drives, there are two types of plugs that come off the power supply. The smaller of the two, is used for the floppy drive. The larger one is used for hard drives, CDROMS, and other drives. Hard Drives, CDROMS, and Floppies are to be connected with a ribbon cable. Older Hard Drives use the 40pin ribbon cable while the newer ATA66 and ATA100 drives require an 80pin ribbon cable. The ribbon cable for the floppy is a smaller version of the 40pin cable.
There are several wires in the lower front of the case that are used for switches and leds. You need to connect the power and reset switches and the leds, such as power and hard drive activity. The wire connectors are labeled. The motherboard will have pins that these wires plug into. Refer to your motherboard manual for the location of the pins and connectors on the motherboard.
Once all of the components and installed, it is time to test the computer before replacing both of the side panels. Connect the video card to a monitor. Connect a mouse and keyboard. Plug power cables into both the computer and monitor. Turn them both on. If the computer starts, then you are all done. Replace the side panels and setup the computer where you want it. If the Computer does not start it is time to troubleshoot.
Some motherboards will not start without a fan connected into the first header on the motherboard. This is generally the closest connector to the CPU.
Some power supplies will not start without a drive connected to them.
Double-check all of the connections. Make sure the CPU, Ram, and Video card are properly seated. Make sure each drive has a power and data cable.
To increase the airflow in the case, you may want to install a fan in the lower front of the case. This will help cool the CPU and other internal components. A plastic fan holder at the bottom front of the case is available for the attachment of an additional cooling fan. A 80mm fan will fit into this case.
To cool a hard drive you will have to install it in a 5.25" drive bay. You will need to purchase a hard drive cooler at a local computer shop. Some kits will support the hard drive and others will require you to install the hard drive using drive rails.
Make sure to ground yourself while installing any computer component. A static discharge could damage a computer component. You can ground yourself by touching a metal object that is grounded, such as the case when plugged in. To make sure, you can purchase a grounding wrist strap at your local computer store.
When using a hand screwdriver and/or powered screwdriver, make sure the tip is not magnetic. A magnetic tip could damage some of your computer components.
