I want to upgrade my Pis to something more reliable and not SD-card based and refurbished thinclients/SFF workstations seem to be a viable route. Does anyone have a cheap source for used hardware like this in Germany? I feel like the usual esm-computer, green-IT etc. are a bit overpriced.
I recently purchased three Lenovo m910q, which are now running as low-power proxmox cluster at my home for a very decent price. Here’s the shop: http://www.manotebooks.de/ Quite happy with it.
