if you want to keep evox their is a hardware way of doing this as shown int he tutorial here:http://www.xbox-scene.com/articles/front-led.php
you don't have to take out the controller ports though if you take just take out the power led's power cord first and then all you have to do is pop out the front of the case as it shows in the tutorial and then switch the wires.
P.S. sorry that last part about the front panel is only for mobos later than v1.0 if you have a v1.1 to 1.6b version the controller ports are attached right into the motherboard itself.
Hope this helps, and don't hold me responsible if you mess up just BE CAREFUL.
oh and btw this is the method I used and it worked out just fine.
