It should be an ATX form factor. I have an 8300 and it's a standard ATX mobo. The only thing you need to be careful of is that there isn't anything proprietary like the front panel connections or power supply connections. Sometimes they use things that are not standard.

The other thing to be careful of is the rear panel connections, your new case may not have a back panel that can support the dell's configuration.
