Could You Fit a ATX12V in a ATX Mid Tower Case?

[Warr]

Just wondering I'm new to PC and wondering if I could use the power supply on my build

Yes ATX will fit.
Mid or full towers.
Micro towers and ITX. The smaller form factors is where they won't fit.
I think some Micro cases can fit a regular ATX PSU though.
