The E210882 sounds like the motherboard model number. What’s the PC model? They might have used the same motherboard in different cases. But from what I’m seeing, the motherboard looks to be a microATX form factor so any microATX motherboard should mount in there. The rear panel might be built into the case or at least not a standard size. So you might have to cut that open to fit a normal rear panel port shield. I would assume you’d swap out the PSU and not try to use the old Dell one so you shouldn’t have to worry about any PSU compatibility. The only other thing would be the front panel connector. Dell generally documents their PCs pretty well. So if you look up the model number or Service Tag, there’s a good chance they list what pins are for power button, LED and so on. Maybe if you do some searching you “might” find an adapter. But probably you’ll have to make your own adapter or splice in some normal dupont connectors.

A cable with a 2 pin DuPont connector on it will fit on your motherboard front panel header. Something like this…
