There’s nothing wrong with my old PC case, except I’d like some USB-Cs in the front panel.
The panel itself is unfortunately integrated, but it’s possible to get additional front panels to 3.5" and 5.25" slots (the ones traditionally used for CDs etc). Here’s one example from akasa with at least one USB-C: https://akasa.co.uk/search.php?seed=AK-ICR-36
It’s perfectly fine if I have to just disconnect the integrated USB-A ports due to lack of motherboard connectors. They suck anyway.
So, please share recommendations for such devices. Let’s not let those old cases go to waste!
There are also pcie expansion cards that can add additional USB headers if you need.
There also exists m.2 to USBC / USB3 headers, or even combinations. As long as you are OK losing an m.2 slot.
There also seems to be 3.2 Gen 1 (the blue connector) to “Type-E” adapters: https://graugear.de/en/portfolio-item/g-ad-19te-90/
