Back-plate for the sound card in place, used some velcro to hold it down as I will be needing to mess with it later in the build, its also a bit more tidy than using the screws on the card to hold it. got this cutter some years back for my model making, helps add some detail to the plastic, also very useful for cutting the plexi Bit wonky as it's not fastened in place just yet.. Same again for the back cover. Ordered some more white plexi, so most the parts will be re-cut using the old ones as a template. After some testing I decided to have the RAD facing the standard way rather than upside down. Just didn't have the room I wanted at the top for all the pipe and fittings.
