My homelab currently includes:
2x Raspberry pi 1’s
A Netgear switch
A drive to usb adapter for a NAS solution
Its not much, but its mine. I have a third Raspberry pi that I plan to use as a firewall and Wi-Fi attachment as the stuff is currently far from any ethernet connection. I will eventually move these from their current location to the basement when It gets louder. It is not currently done and I do not expect it to be for some time.
