Everything about it is proprietary and not working with a "standard" case.  I would also buy slot covers for later since most cases these are break away. [URL] [IMAGE]   If I did change the case I would use a reasonable cost case like this one. [URL] [IMAGE] The rear panel on the DELL 36XX series is not removable its built into the case.  On many models the back plate for the CPU cooler can be built into the case as well.  Dell fans are not always wired standard so you may need to check the pinout for re wiring those or using the dell fans.   It can be done but its a lot of work and its not supported. Pinouts are not documented and the power supply needs a conversion from MODDIY to make the 24 PIN EPS12v connector into 8 pin.
