I'd write something about my experiences, but it was all so long ago now that I doubt I remember enough details to make it interesting. Still, something like this would be a fun project to do again in some ways. I've even toyed with the idea of doing something like the guy in this talk, but with an AS/400. The biggest reason I never did, other than the size/power/cooling issues, was the software licensing. I imagine an actual OS/400 license is crazy expensive, and if I just wanted a Linux server on vintage hardware, I would just fire up one of my extensive collection of old Sun SPARC boxes. :-)
