Getting the ATX panels was a real nightmare.
If you want 100K, no problem, they are sub 1USD.
The tooling cost is huge to cut out the holes.
Eventually I found a supplier in Taiwan who would laser cut them from blanks.
Price list on my website shortly as well shortly, I need to charge Swedish VAT at 25% for EU shipping, so the prices are about the same. These are sold at cost.
