That's what I'm wondering too. Seems to perhaps not be a total disaster if M3 screws will work instead of the 2.5s. That shouldn't effect too much else within the board design/ performance/ aesthetics.... right??
the acrylic spacers, if drilled for exactly m2.5 could be a problem
The bevels in the top case may also be too small for the screw head to fit in which might leave the screw head sticking up also.
Ok, thank you realists, you've sufficiently harshed my mellow.
I'm a pathological optimist, was hoping the ripple may not be that bad.
I didn't think about the diameters of hole within the the case recesses in the bottom case and the screw head. Obviously that could all be very tricky and necessitate factory involvement. Tally810- I'm not sure I understand your comment on the bevels in the top case being a concern as well... aren't there just the threaded holes for the screws to grab on the top case?
Here's to hoping that 27 has some luck with the M3s fitting naturally or being Dremmel-able so the boards as-is will work. Re-machining holes in the case and/or spacers would seem to send this a bit sideways for a while... Fingers crossed, 27! Please keep us posted.
