You will now have to put the mainboard with the bolts underneath at the top of your case. To do this, first mark off where each bolt is. Once you do that, take some measurement on your main board from the drive on the board from all angles.
Then use your measurements to mark out a hole for the drive to come up through on the top of your case. Cut it out and if the drive does not fit through the whole trim it up until it fits.
Now put on more nut on the bolt so there is one bolt outside of the case and one inside the case. You may want to adjust the bolts by putting a disk on the drive, and adjusting the nuts until the disk is level and low but not touching the case. You may want to cut off any excess bolt above the nut.
On the inside, you need to cut a piece of your case away to make room for the audio/video port. If you have room, then you can skip this step.
The next step is to secure the top cover. A small notch needs to cut on both sides for the cover to fit correctly.
Put the same notch on the other side also.
The next step will require some coordination of where the mainboard at the top of the case is situated. Make a cut similar to the one below and put your cover through the cut:
Currently, the hinge system will not be used. To open the cover, you will just lift it open. I will try and update this with a better method in the future.
The next step is to mount the controller ports to the front. Find an empty 5 1/4" empty drive cover and measure off the Playstation controller ports. Take your cutting tool and cut the small hole. Glue the controller port to the bay and let it dry. If your case is small, you may not need to extend the cable for the connectors to the front of the case. The 9001 model that we used was long enough to reach over to the front expansion bay. Other models have the boards designed differently so these cables would probably not reach, check first before installing:
Your final result should look something like this:
The last step is to get power to this unit. To do this, we used the rear expansion slots. Find a blank cover and cut a hole into it like so:
Take the power supply that you removed from the Playstation casing and screw it into the cover.
