Forgot to reply to this. CRT-free since 2004 or so (and at work since
1998 - and boy was that IBM 9516 expensive!!). Case is a fairly
serious Antec with no gaming "features", so good there. Current mobo
was a cheapy and does make noise. I've tried a few ferrites here and
there but A) the noise isn't *that* bad and B) I've decided that the
current board is term-limited and it's just not worth the fuss.

Expect to use VirtualBox on a Linux base. It appears that the latest
versions of VB can deal with the images that are created by VMWare's
P2V. We'll see if that holds up in reality. :-)
The interesting bit will be the SIIG as it will be linux underneath
not XP. Linux is pretty good about "just working" with serial ports
of any persuasion, but again, we'll see if that holds up in reality.

Now that could be a show-stopper. Are you running MMTTY, et al, on
that soundcard? Because I expect to use this system as my Radio PC,
and being able to decode RTTY (and PSK) are kind of critical to that
Thanks for the tips!
