Great support!
Having bought a couple of CK1s for some home lab hosts the team at DroiX have been great when I have needed support. First, some time ago, they were happy to support me with hardware questions even when I had replaced the OS with something non-standard. Recently I needed to source a replacement fan for one of the CK1s out of warranty and again the team came up great, quickly finding a spare part and getting it shipped to me.
My needs are a little niche but definitely I'll be coming to DroiX first when I'm in the market for mini-PC and home lab systems.
