Another backer & owner of the original NDLR here. News of the chance to upgrade the unit to the later specs is very much welcomed. As another backer has mentioned, I’d also like the option to drill, mount & solder a power switch if this is feasible? Dimensions and required placement location could all be covered in a drilling/mounting template to avoid errors. And why not let your new backers show off their upgrades with a Conductive Labs decal to go on the rear facing panel, something suitable that shows the unit has been given a new lease of life! Cheers and best wishes!
