Making Side Panel Templates To Scale:I translated the CAD design to hard stock for the side panel pieces that will go on the tempered glass panels. Its pretty easy to do as its literally transferring each measurement over. I've decided to use thin steel stock to make all of these pieces. It'll take longer than making it out of acrylic but, I think it'll fit the design better in metal.
To adhere them I will more than likely use heavy duty transfer tape thats used typically for adding acrylic side panels. That way if I ever have to remove them; I can without messing up the tempered glass. I also remembered that there are two holes in the tempered glass which are used to mount it to the case. I will take advantage of these to help hold the back pieces in place. The picture below are of the templates after I used them to cut the pieces. I will update the logos once I make more progress on them.
Update: Side Panel PiecesI decided to use my air cutter to cut the metal pieces for the side panel. Im trying out a new design technique for these pieces so it will be interesting to see how it turns out. The panels are made up of two solid back pieces and layered top pieces that have 1–4mm spaces between each piece. The varied 1–4mm gaps will look really neat once everything is painted and mounted. Here's the rough cut pieces before filing and sanding.
Update: Rear IO/PCIe Cover (Bottom Pieces)The bottom two pieces for the rear IO/PCIe cover were made using templates made out of hard stock. I then transferred the templates to metal sheet stock and cut them out using my air cutter. After the general shape was cut out, it was time to use my bench grinder to fine tune the cuts. Once I had that finished I run them through a process of filing and then sanding the edges to make them exact. Then, onward to test painting and mock-ups. As you can see I was able to mockup the 4 pieces I have finished. There will be a few more pieces that I still need to build and mount.

Modder Tip: Bending MetalThey need a 45° angle at a specific point which is pretty easy to do without a bending brake. I run a line along the edge I want to bend and then use a counter top to bend it along. The bend edge will match the edge your bending it against. If your countertop edge is a gradual bend; your metal piece will have a gradual bend. I needed a tight bend so I used the edge on my workbench.
You'll want to clamp the top edge so that it stays flat against the top of the work bench. I usually use a piece of steel with a clamp on each side and then use another flat piece of steel to push against the other edge. This helps assure that you have even pressure along the entire piece you are bending. There are lots of tutorials online that show step by step on how to do this.
