I would check out your laptop, especially if it’s somewhat new. I have one that is dual booting from an M.2 NVMe drive and a SATA SSD. Even if it didnt, I have easy panels that pop off when I wanted to swap.
Been to a fair amount of castles in the past few years, but this is top of my list to visit. No plans to be in the area anytime soon, but I hope it’s sooner rather than later.
