So based on the compatibility page, I might be okay with the 5P. The page specifically mentions the 5PX. Anyone using this UPS? When looking at Eaton UPS's I excluded any of the older ones that use the BCM driver since that driver provides little functionality as I've learned with the 5110. There's also the Evo, but I would prefer to have one with ABM. I'm open to other models (or even brands) if they work great with NUT and are decent hardware-wise overall. I'd like better battery management than I'm used to (darn Smart-UPS's), so an always on fan and temperature compensation would be best. Can't be too expensive though, the 5P I'm looking at is ~$600 which might be a stretch as it is.
