That’s really cool! I have a bunch of old hardware, unfortunately I can only bring them online when I want to play with them and don’t have any permanent space.

Do you know how many watts you consume? Are alternatives to old enterprise gear from eBay going to be cheaper from an electricity point of view?

I'm kind of guessing here but:

-Cisco ASA 5510 firewall - 100W

-Dell R610 running ESXi - 400W

-Old Dell 2950 full of 2TB drives running FreeNAS - 400W

-Cisco 'Small Business' 50 port managed switch - 100W

-A couple of 4U server cases containing the guts of obsolete gaming systems, repurposed as assorted -servers - 2 x 300W

So, maybe 1600W under medium load? A 15A circuit can deliver 1800W max., so it would be occupying one whole circuit.

Hardly worth it, considering the noise, heat, space, and power. Old enterprise hardware gets given away for a reason.

yeah, I considered holding onto a pair of old 2950s but ditched them considering my peak electricity rate is 43c kw/h. This setup makes me shudder.
