I'm hoping I'll have the opportunity to build a similar machine soon and am
wondering about the choice of 64 bit distributions.

Gentoo is obviously a possibility but I'm also condsidering Debian. There is
also a 64 compile of redhat sources somewhere around, but I can't remember
what they call it offhand.

If anyone has opinions about that, I'd be happy to hear.

regards
Iain
