I’ve recently bought a nice old AT case to refurbish it as a new “Home” for my 486DX.
After retrobrighting* the front and painting the hood I’ve noticed that it requires some special mounting rails for all the drives (both 3.5" and 5.25").
First I’ve tried some rails from a fujitsu case I had lying around but they didn’t fit properly (with no chance to modify).

I took measure and am looking now for the proper rails (before I start improvising).
Please find some images below …
Hight: approx. 25mm
Width: approx. 4mm
Length: ??

Does anyone know that case and have an idea what specific rails I need?
Or, if anyone has a similar case, a image of the rails (with measures) would do as well!

(maybe my neighbor with his 3D printer can help me)

* BTW: this time I’ve used a black builders tub (covered with a transparent bag) with liquid Peroxide solution and it worked far better(!) than the paste I’ve used until.
You’l need a lot of liquid (approx 10 liters, thinned to 3%), but I’ve filled the remaining liquid in two canisters for later reuse.

Won't anyone know/have this case?

They're not made out of unicorn horn or anything though, strips of any more or less rigid material of convenient thickness cut and drilled to suit will do... Popsicle sticks even.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

Yes the problem with these rails is not figuring something out to hold the drive in place, but how to secure it from sliding back and forth.
Some rails have "ears" that snap in place, this particular case looks like it needs L-shaped rails screwed at the front.

Looks easy enough to mock up a design using sheet metal. Cut out thin sheet metal with some nibblers to the size and shape it needs to be, bent over with the ears to secure it to the front. Then put it in Sketchup or another CAD software to account for the thickness it needs to be and have some rails 3D printed.

Alternatively, you can use thin cardboard or even cardstock paper to make the prototype rails to get proper dimensions for the 3d model creation.

With 3d printed stuff, it might take 2 or 3 tries to get it exactly right.

This case requires spring loaded latches attached to rails due to rectangular openings in front of rails built into the case drive cages. Not screwed to the case.

I agree Pentiumspeed ! Have seen some black plastic wide types with metal "mounded " spring type things that probably were used in a similar case, unfortunately cannot find any in my box of rails to show as an example....

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

Already tried these but they won't fit in any way.

Guess that case isn't very common 😉 and I'll habe to start improvising with some strips of wood.

This is as close as I have - these are the 3.5 bay ones (5.25 are similar but bigger, can't find them atm). Wood strips fixed to IO blanking covers (for the angle piece) should work OK.

I've already formed some rough plan that might work 😀

- I will first attach the front case-cover and try to fit the drives (CD+FDD) in place.
- Then I will estimate the placement of the drives and attach the wooden strips accordingly with double sided tape to the drives.
- If this fits, I will use some small screws (or maybe hotmelt glue) to hold the drives/strips in place.

... but I really would have preferred some proper prefab solution instead of improvising.

Once you make something that fits, draw it out with all the correct dimensions. There are tons of companies online that can waterjet/laser cut your design out of metal. I've used this company before for metal keyboard plates, and they're reasonably priced. https://www.bigbluesaw.com/ edit: they're US based, but I'm sure your country has similar options available.
