Once cut out I lined up where the psu of the 360 will need to enter the void and marked that up.
With it being away from the edge I decided to hide it a bit better buy leaving the front of the tray on
You can see above the entrance point for the 360 psu to go into the void. On this pic you will see where it enters the tray
Now I had to cut out the 120mm fan hole for the fan going near the pc i/o panel
I have gone as far as I can at the moment with the chassis as I'm waiting for the 1mm Aluminium that will make the 360 motherboard tray.
