DNA250 / DNA200 / DNA75 v1 Faceplate - metal option only. Mounting hole = 20mm x 72.5mm (for accuracy measure mounting hole height and width of the faceplate you receive before cutting the hole in the case - the ones I have received have been about 1mm less in height and about .5mm less in width than the actual measurement).
Requires 3x #0-80 screws 1/8" long to screw the DNA board to the Faceplate. The screw holes in the Faceplate are NOT tapped, so you will need a 0-80 tap to thread the screw holes or buy self-tapping screws to thread the screw holes.
Also requires a DNA v1 Screen Holder for mounting the screen to the board: https://www.shapeways.com/product/27HHBDZN4/dna200-v1-screen-holder?li=shop-results&optionId=57375052
