How can I create a rack with PCs

Question

Here's what I need to do: I want to have multiple desktop/laptop PCs stored in minimal space I should be able to attach a peripheral device to each PC. Should be able to access the PCs easily to attach/detach peripheral devices I would like to use a multiplexer to access each PC with the same keyboard+mouse+monitor so I save on monitor space(and wires, and cost). It should be expandable vertically because I don't have desk space to expand horizontally.

Think of it as a Server rack, but I am not going to use individual racks. I want similar compactness but with individual PCs. The cabinet should be secure(ie. Cabinet should be lockable)

I have searched for cabinets that allow me to store whole PCs but it doesn't look like this is easily available. Anyone who knows something that matches? or have build such cabinets?
