With a customized LGA 775 adapter kit, XP-120 is designed to fit all socket T (LGA775) motherboard. So far, we have not found any board that is not compatible with XP-120. If you've found any, we would appreciate if you could report them to here.
* All ECS socket 775 motherbaords require a bigger case (at least 25mm from motherboard edge to power supply unit) to accomodate XP-120.
** The screws came with the LGA775 RM package are too short when it is mounted on an Asus Stack Cool motherboard. The screws need to be about 1/8" or 3mm longer. Users reported that these screws are available at their local hardware store.
*** Large fan bearing heatsinks (80-92-120mm) can encounter problems with motherboards with sockets close to the edge of the motherboard and some cases with power supply brackets. Another potential problem with these types of motherboards can be large fans mounted in the bottom of the power supply and without the fan drills recessed.
