i speak about brand like lenovo, HP, DELL ETC
the easiest way would be to open the case and look inside but for stuff on ebay or amazon? you can ask the seller but you dont always get a answer and when you do they sometime just told you find it out yourself.

if i take this as example
https://support.lenovo.com/ca/en/documents/pd013522#pow
they give a lot of info but i cant find if it have ATX power supply or fit in ATX case.
they probably are ATX compatible because i had like 25 lenovo computer and all of them where ATX compatible but it can vary from one model to another

so if you guys have a way i would appreciate that you share it with me
