Case swap has some drawbacks. 8940 board is not rectangular.  You will lose all original front IO USB and audio ports.  Note that board does not have usb 3.0 header to allow you to plug in a front usb cable. then the TFX psu does not fit most cases that have better air flow.  Although presumed 6 pin ATX + two 4 pin cpu pinout of 8940 is known, it has not yet been verified I and reported. one redeeming feature is the 5 pin power button header on motherboard for which presumed pinout is known, and verification is risk free.

Hi, I am wondering if I could transplant all or most parts from a Dell XPS 8940 into another pc case with better airflow? I know I will probably need a new PSU. Thanks
XPS 8940 into another case?
