IRIX rocks, I have an indigo too, it's headless in the corner acting as an nfs server right now. I think that some of the older indigos had the y2k bug (that's actually how I got mine from my old job, they were too lazy to maintain and patch them) but it can be patched easily. Indigos make decent webservers, that's what mine was being used as before it was mine. These days with cheap pc parts (don't flame me for that) it makes more sense to run a linux server on a sub $300 box since it will actually handle a higher load as a webserver than the indigo will, but if it's for low traffic uses by all means take advantage of what you've got.
