An ATX (or even an ITX) PSU may be up for the job....
Not directly! Powering the Pis with an unfused high current Power supply is dangerous!
You will need to include a proper fusing on each output and include everything in a decent cabinet...
That is probably not something for everyone.
A good solution would have been to re-use a charger from an obsolete laptop. They usually deliver 3-4A at 19v.
With a buck converter as that one for each pi :

you can power around five Pi 4 and seven Pi 3, maybe even more if you don't use a lot of periphery.
