Looks very cool! Seeing the limitation in how many of the UPS sockets can be used, I'd say it's a little bit of a shame not to have used high amperage IEC connectors - e.g. C19/C20 ones. Most UPSes have options to work with these natively rather than having country-specific and often painfully shaped connectors (e.g. UK sockets are huge!)
