I’m game - retro SGI hardware FTW! Indigo, Indigo2, Indy, O2, Octane, all crazy designs. l miss my Frankenstein MacBook original with 9600 baud modem and OS6. Or the Macintosh color with 9" CRT. Then there’s the Amiga, the NeXTcube, DEC Alphas… and on and on… I remember the liquid cooled Crays, thos were fun.
I am still considering taking an SGI Indy case and using it with a complete mini-PC inside. The thing I never did was look to see if the startup sound was admitted from the motherboard or if it’s some external device inside the case. I would definitely want the startup sound :)
