I have one as my home router and got an additional two to run as GlusterFS nodes and couldn't be happier (well, Gluster performance is really unsatisfactory with ~50MB/s from these two running in replicated on 1 LUKS-encrypted SSD each, but I've realized now that probably I shouldn't expect much more with this kind of setup and you really need to run distributed on larger number of smaller nodes to make Gluster performant, so can't blame the APUs). Now I'm having a hard time to decide what I should go for for additional worker nodes in my cluster - go all-in on PCEngines APUs, Odroid H2, Udoo Bolt or a larger number of some incarnation of RK3399 SBC (Khadas VIM3/NanoPi M4/Rock Pi) or even Raspberry Pi4s - or if it's better to wait a bit for some of these new AMD SFFs. If power-consumption, space and noise wouldn't be a factor it'd be a no-brainer to get two or more 19" rack servers, but that's a no-go. I have a feeling that the playing field for small-form-factor, power-efficient and quiet compute clusters is going to change dramatically soon with new products based on AMD and ARM, but also not sure if it's worth waiting if I want things up and running by this summer.
