Back in the day, quite a few SS10 clones (using actual Sun SS10 motherboards) came in a painted all-metal case manufactured by Litec. There were a few other all-metal cases used by other OEMs, too. In addition, the Axil S311 appears to have used a plastic-coated all-metal chassis. Unfortunately, those original Litec cases are now ***much*** rarer than even Sun SS10s. -- Mike Sent from my Galaxy -------- Original message -------- From: peter%easthope.ca@localhost Date: 08/09/2025 12:42 (GMT+00:00) To: port-sparc%netbsd.org@localhost Cc: peter%easthope.ca@localhost Subject: Polymer Sparc cases.

My best guess is polycarbonate. https://en.wikipedia.org/wiki/Polycarbonate It can not be solvent welded. Brittleness can result from depolymerization. When long chains are broken, there is no simple means of re-polymerizing. Poly(methyl methacrylate) has good long term stability and solvent welds very successfully. https://en.wikipedia.org/wiki/Poly(methyl_methacrylate) I've used dichloromethane to solvent weld acrylic. https://en.wikipedia.org/wiki/Dichloromethane Work in a fume hood or outdoors. > In any case I don't see a "good loking" way that can also be > decently strong.
