Take out the case from the cardboard box and put it down on a clean, sturdy surface. To open the case remove the sides by unscrewing the two thumb screws on either side panel while gripping the handle groove and sliding backwards and then pulling away from the case. The motherboard tray is attached in the back by four thumb screws which you should also remove so that the case will be completely open for you to work with it.
Before beginning putting the computer together, take out the small cardboard box contained in the case. This box has screws, face plates, and other important trinkets.
A power supply is a necessary component but does not come with the case by default. If you ordered one to be installed with the case, you can skip to the next section.
Guide the power supply on the support rails at the top and rear of the case. It should fit up against the back of the case snugly. Make sure you don't inadvertently block any of the fans on the power supply; it must be oriented so there is a fan and power connector socket visible from the back of the case. Some power supplies also have a fan which should face down towards the bottom of the case.
Hold the power supply to the back of the case with one hand and use four thumbscrews from the small cardboard box (that came inside the case) to fasten it.
You should have taken the motherboard tray out of the case in the first step. If you haven't, refer to "Disassembly" before continuing with this section.
There are several brass motherboard mounts in the bag (they are approximately the size of screws). Take between six and ten of these and put them in the appropriate places on the tray. Screw the mounts in by hand but make sure they are in firmly. To get an idea of which mounts to use, you should try to put your motherboard over the tray and see which mounts line up with holes on the motherboard. Six mounts should be sufficient but feel free to add more; less mounts could be dangerous, so be careful.
Check to see if your motherboard fits the I/O plate included with the case (above the PCI slot openings in the back of the case). If it does, you can move on to the next step. Use a flathead screwdriver to push down the corners of the I/O plate and nudge it out (in this case, out is in towards the front of the case). Put the I/O plate that came with your motherboard in the place of the one you just removed by pushing each of its corners in. Each corner will snap into place to let you know when it is fastened.
If you haven't already, it's suggested that you install your processor, cooler and RAM (but not PCI devices) on the motherboard prior to doing this step: Guide the motherboard gently into the I/O plate and onto the brass mounts. The holes in the motherboard should line up with the mounts. Put a screw in each of the mounts. When you're done with this step, the motherboard should be secured on the tray. Slide the tray back into the case and re-fasten it with the four thumbscrews you took out earlier.
Use a Phillips head screwdriver to remove the eight screws holding the front bezel in place. It is suggested that you then remove all placeholder faceplates that came with the case. You can remove them by squeezing both sides and pulling outward. Note: You should refrain from installing hard drives until the next section.
Slide each drive into place using the guides on either side. Screw them in tightly with at least two screws per side per drive. When all drives are installed, replace placeholder faceplates where appropriate.
Push the bezel back into place and tighten all eight screws to secure it.
Near the front of the case at the bottom, there are three thumbscrews holding a drive cage. Remove this cage and put your hard drives (up to five) in it. Use provided screws to fasten the drives and replace the cage.
Optional. If you wish to have pass-through ports (they are located on the front bezel), you can use the included Firewire and sound (output and microphone) pass through cables. Use the included PCI faceplate which has a hole in it to send the cables out the back and to the required devices.
Optional. If you wish to use the front USB ports, it is necessary to consult your motherboard's documentation to determine the orientation and position which the USB cables must be plugged in with.
From the bezel, there are several small plugs which must be connected to your motherboard. These connections are motherboard-specific so you will again need to consult your manual. This step is not optional. These connectors enable the bezel power and reset buttons as well as power and hard drive lights.
Connect the big ATX power supply cable to your motherboard (this is a large bundle of wires which connects to your motherboard in one big plug). Connect any fans (on your CPU, from your BIOS, from your video card, etc.; not including case fans) to the motherboard fan connectors. Connect all drives and case fans to the power supply and to IDE cables as necessary.
Add any PCI/AGP devices, such as sound cards, network interface cards, and video cards, to the motherboard. Use included thumbscrews to fasten them. Hold onto the blank placeholder plates that you take out in case you need to re-use them in the future.
Put the sides of the case back on and refasten them with the thumbscrews you took off earlier. Connect the power supply to an outlet and hook up any other peripherals that you require.
Congratulations, assembly is complete on your Directron 301T3.
