RE: Polymer Sparc cases. Was "Re (2): Removing the video card from the ss 10."

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.-- MikeSent from my Galaxy
