IIRC $2k for the z114, $1 for the z800 and a few hundred for a one way moving truck rental I moved it myself, and maybe a few hundred for the ds6800 which I got lucky when it was FICON enabled the auction did not specify. There are three off-label mainframe support companies in the US that broker machines and parts for companies trying to bleed out their machines due to some transition plan or whatever. I've made acquaintance with one of them so I got the z114 for a great price because it wasn't suitable for any of their common customers and they were able to move it quickly from decom to me.

For the HMC I recall reading this in a manual or hearing it from a mainframe professional but I can't quickly cite it. It may be for some things that a home user doesn't necessarily need, like remote access. Can you access the z/OS System Console from the SEs, that is the only critical thing I can think of.
