This post is about buying an IBM z114 mainframe (picture 1) but should translate well to any of the IBM mainframes from z9 to z14.
Buying a mainframe takes time. I never spent so much time on a purchase before. In fact - I purchased my first apartment with probably less planning and research. Compared to buying an apartment you have no guard rails. You are left to your own devices to ensure the state of whatever thing you are buying as it likely is sold as-is. Unless you are buying refurbished the seller will likely have no idea of how to verify the item and might even lack the equipment to power it on.
