Find your local liquidation auction house. You'll see a lot more of the types of atms that show up at cash only businesses than bank location style atms, but sooner or later, one will show.

Yes! Look on the DEFCON channel on YouTube and watch several live demos with ATMs that were purchased second-hand.

Just keep in mind that it's very heavy. Very. Like your building's construction code may not allow that much weight per floor area. Shipping or mooving it around would be similarly "fun".

They make motorized hand carts ("dollies") that make it easy for a single person to move large safes. Either with motorized wheels, or a motorized actuator that lifts a second set of wheels up and down which makes it possible to go over curbs and other obstacles.

It would still probably be "fun" (not easy) for someone who hasn't done it before, but not impossible.

Whilst that's true... It doesn't change that the floor you're moving it to is probably not rated for the weight.

Picking it up only solves half the problem, and the easier half.

I had an acquaintance whose side business was running ATM's in convenience stores in California (the fees are outrageously profitable) so I assume it's possible to buy/rent the latest models for personal use and hack it all you want.

Hacking a rented device likely violates the contract and perhaps law.

There is a great youtube video about buying and converting a second hand ATM https://youtu.be/nHDpzczgdo0
