These use standard ATX power supplies (unlike most newer OptiPlex systems) so as long as you find one that physically fits the system, you can upgrade to a non-Dell ATX power supply.
You will need to be more specific about what you want to upgrade. Memory and storage can be upgraded.
If you want to upgrade to a system that fully supports Windows 11, that answer is no -- there's no CPU you can use in this system that supports the requirements of Windows 11.
