Man, if only copper was easy. One of the gotchas is most connectors for CPU, graphics cards, and chipsets tend to use the G1/4" ends up having metric on the other side. 12mm or 13mm. Most copper pipe is .5", which works out to about 12.7mm. You have to be really picky with couplers if you want to use copper. PTEG/Acrylic is less great for things that would be banged around and a pain, compared to if you know how to actually do copper.

Or you just use actual metric copper pipes in 12mm....

  Good luck finding those easily around here!

    Yeah, it's one of the more practically relevant downsides of not really switching to metric. It could start with mandating metric-based norms for building parts in new designs for federally-funded construction, as well as mandating in consumer protection regulation that the metric measurements have to be no less prominent than non-metric units (well, technically that'd be about SI units). At some point potentially requiring operations with large-enough warehouses to offer the metric-norm equivalents for parts according to non-metric legacy norms, if they reach some threshold with inventory turnover on those parts where it'd not be a big burden to also offer those metric equivalents. But yeah, I know the feeling of foreign norm components being hard to get, from when I tried to get the screws used for consumer-grade camera tripod mounts. They are iirc 1/4" machine screws. Roughly like M6, but far from compatible.

      Yup, or even equipment with mixed standards that are kinda close so you have to start pulling out multiple thread gauges just to figure out WHY you're particularly screwed, and for how long will you remain so. Plumbing is rife with it near as I can tell. Semi-random differences in thread pitches, metric vs standard, etc. everywhere.
