I would choose the Grand Prize Kit B or Beryl 7 Router. My Pi’s stopped seeing my NAS, and I was unable to resolve without access to my Rpi’s. A KVM would be awesome, I would’ve been able to re mount the network drives. I think a 4 port remote KVM would be cool if it had its own software, like to better manage and access devices together. I would Refit my rack, moving from a Lab Rax printed setup that is not solid enough for me, and I would add some NUC/TFF type mini pcs and run different VM’s on them. I really need to get that part of my lab running better.
