I have a dedicated machine for playing old Windows98 games as well though
mine is an Athlon XP 2800+ which is also my backup server.

I also have an even older K6-2-500MHz system that I use for DOS games
instead of dosbox.  It has an old 4.5GB Quantum Viking 2 SCSI drive (yeah,
I have had it for at least a decade) but it also has an Intel e100 NIC
and an old Gravis Ultrasound PnP with 8MB of RAM on it. For games that
don't need saving I just network boot them and leave the hard drive spun
down to preserve it (also, it is loud).

I made a generic 128MB DOS bootable hard drive image a while back.  Now
when I want to make an old DOS game net bootable I just make a copy of
that file, loopback mount it, add the game, gzip it, and add it to my
pxelinux menu.  The Intel card will DHCP an IP, TFTP download the image
file, un-gzip it, and then mount it as a RAM disk for C:.  I have used it
the most with: http://en.wikipedia.org/wiki/Tyrian_2000  Besides, what
would DOS do with 512MB of RAM ;)

I do have dosbox installed too.  I have used it on my Eee where I don't
have the luxury of extra old computers.  I have mostly used it to play
http://en.wikipedia.org/wiki/SSN-21_Seawolf but it doesn't do the best
job.  The game runs slow to the point that it lags on some keys and
occasionally duplicates keys, zooming takes forever, and the aspect ratio
isn't right.
