Too Old to Go Further?

So far she’s been handling Monterey well with the upgraded components (500GB SSD and maxed the RAM, re-pasted the chips). The only somewhat major issue is the legacy WiFi card not working properly, but solved that with a USB WiFi adapter. I know of the issues with the USB 1.1 controller not being supported after Monterey, so curious how to get around that. Otherwise, would this one be able to handle going further, slight chance of Sequoia? Anyone running it on this machine? (Yes, it’s the white polycarb body)
