Yesterday I got an old Silicon Graphics O2 - fully working. Its a MIPS5000 @300mhz, with 192mb of RAM and a 4GB HDD, with IRIX 6.3 installed. So far I have had a google and can/could update it to IRIX 6.5.22 or Debian and from my bits collection add upto 90gb of extra storage. Any ideas - please no use as a case fore newer PC as it still works perfectly
I hate to say it but you won't even get a modern web browser to run on it. As you said the case is worth modding, but the hardware is too obsolete for anything useful.
