For what it’s worth, a “DIY” buying option of the HL15 / 8 / 4 hardware is something that I would personally be interested in for the future. Framework sells their laptops with this option and I really appreciated having this curated option from them that I could assemble myself. I think there’s enough of us in the 45HomeLab market that would also appreciate an option like this that’s in between the Full Build and the Chassis/Backplane currently available.
