The e520 is a "BTX" style, not ATX. There are no current production BTX style motherboards that I know of. That, for all practical purposes, eliminates the e520 case.
In addition, the e520 front panel connections are not standard ATX. They are Dell proprietary and undocumented. The rear motherboard I/O panel on most (all Dimension models that I've seen) are built into the case, not an insert.
You're also need to buy a new license for Windows because the license you have now is tied to the e520 motherboard.
And you likely will have to clean install Windows because what's on your HDD now probably won't work with any new motherboard. So back up your personal files on external media and make sure you have the product keys for your apps because you'll have to install those too.

Cases are cheap.
