Hot swap sockets are usually held in place on the pcb by solder, if you're going with a hardwired build I highly suggest skipping the hot swap sockets.

If you really want to use hot swap sockets, I suggest either designing and/or buying a pcb that has the pads for hot swap sockets, or you can model one of the hot swap sockets and print a "mold" for the bottom that "cradles" it
