I have old software that can only be run on the AT motherboard. I don't have an AT case and have a dead AT PSU. I'm on a budget, so I can't buy a new AT PSU. Is this http://i.stack.imgur.com/5bjpN.png the best way to connect the ATX case's buttons to toggle the ATX PSU?
odd circuit, bizar to hook up the reset to the power. meh
I think this is what you need https://www.amazon.com/20-Pin-Power-Supply-Ad … e/dp/B01EDGS0KI
Just add an SPST switch to the two loose cables, green & black.
Right to repair is fundamental. You own it, you're allowed to fix it.

For the power supply, you can use one of these: https://www.aliexpress.com/item/1005002434776403.html
You hook up the spade connectors to a toggle power switch. (SPST switch type will work)
For the case, you'll probably want to use a ATX size case so the I/O shield and slots line up. You can use one of these I/O shields: Re: ATX I/O shield models for 3D printing -- if not, you'll have to cut some metal on a solid/blank I/O shield: https://www.amazon.com/SuperMicro-MCP-260-000 … /dp/B003TZQK34/ -- or use a stick on cutable I/O shield found here: https://www.aliexpress.com/item/1898100596.html
For mounting, you'll likely need to add/remove standoffs in the correct locations, depending on the board. New holes can be drilled and tapped to accept a standoff. The thread for common standoffs is #6-32 UNC.

I want to connect my ATX case's buttons to control the PSU, as in the schematic. @wiretap
The ATX case button is momentary. The easiest way would be to hook up a small latching relay to it.

Since a latching relay is dual coil, I use pwr button for on and rst button for off?
On cases I've done this with, just getting a latching 7mm x 7mm switch is usually sufficient.
Most ATX cases I've got have a momentary switch like this the springy kind, which can be easily replaced with the latching / locking kind of the same switch.
But you would need a circuit or something if it's a little pcb mounted tactile type momentary switch.
