In order to accurately drill the bolt holes to attach the perforated aluminum to the side panels, I fabricated a drill template from some left over flat bar stock and a drill bushing I had lying around the shop.



A couple of spacers was used to quickly and accurately place the jig on the work piece (to avoid having to measure/layout the location of the holes).




Some .063 perforated aluminum cut to size:





To accurately cut the rounded corners on the side panels a router jig was fab'd from a piece of the corner round used on the body of the case, 1-inch u-channel and a couple of 1-2-3 block hot glued to some particle board. Two strips of Mylar from an old drum head was used to smooth out any irregularities.




Tah-dah!

Another requirement for this case is a hidden door latching mechanism.

Look Ma! No latches!




A length of .125x.75-inch flat bar was bolted to the bottom of the door to act as a lip that will hook into the u-channel along the bottom of the case, for example:




Along the top of the door, there is a piece of angle with three "hooks", which were routed out using a cobbled together router template.






A thick piece of flat bar was filed down to where it'll slide easily inside the u-channel along the top of the case. To that three "posts" were bolted to it. When slid forward, the posts will engage the hooks.

A large area of the right side panel was cutout for a 16x15-inch acrylic window.

I made a mistake, placing the false back too far into the case, which required having to re-fabricate the back sheet. But I figured I could take advantage of the situation by improving the mounting of the motherboard tray, by fastening the tray to the false back with a 7/8-inch long spacer.



I don't remember if I already offered this tip before, but I try to reduce the wear and tear on my 1/2-inch flush cutting router bit by first rough cutting with a 3/16-inch spiral downward cutting bit.

A PSU mounting plate was routed out of a piece .10-inch thick aluminum sheet with the help of a custom template.

In order to accurately transfer the locations of the PSU mounting holes, threaded hole transfer punches (mcmaster.com part # 3385A31) were threaded into a PSU.






And then the PSU was carefully centered and pressed into the sheeting, with the end result being a perfect squarely mounted PSU.

Interesting way to get the PSU mount holes drilled out.

Another router template was made to cutout the areas for the PSUs out of the back sheet. A guide was clamped to the bottom of the template to keep the cutouts perfectly aligned along the bottom.

Turned out that I needed to cut one more slot out of the bottom shelf. But the last time I used my wooden "small slot" router template, I somehow managed to crush one edge, so I quickly cobbled together a new out of some left over t-slot extrusion. I'm really loving using these t-slot extrusions to make router templates - fast and accurate!




Here's a teeth-shattering video of me cutting out the slot.
