Even if it's a custom build? As far as upgrades go it is my understanding that the OEM is bound to the Mobo but you are free to upgrade everything else. From the feed back on new egg it appears that you can change the Mobo but you must call Microsoft first to have the OS unbound. If it really is illegal then the name of their product is misleading.
