If nobody wants it as parts, you can mine the boards for rare metals, racks for steel, and all the power and signalling cabling for copper.
WARNING: There's a whole lot of Hazmat involved - older buildings have asbestos, and there's a lot of Lead in batteries and old cables, and other stuff you can't just crush and release.
And if the building has a Fenwal Halon fire suppression system that has to be disarmed and recycled too - between recovering the gas and selling them the used bottles it will pay well for getting it done. DO NOT trigger it to 'make it safe', you can get a $10,000 to $10+ Million EPA Fine for deliberate venting CFC's.
The batteries and their racks are good for solar storage if they aren't too old, and recycling the lead if they are. They have date codes.
Generator plants and all the power gear (48V switchboards and chargers) are the same - Resell if in good shape, or sell as cores for rebuilding if too tired.
There may be several offline 120/240V power inverters - sell it as a package (Chargers, batteries, inverters, generator) to a ISP Hosting company for a data center.
Building electrical panels can be recycled too - Look for a PEARL electric switchgear recycler near you, like 'Bernard & Son' in Los Angeles.
