Here are the specs for the gxi:

You have a pentium chip running at 166Mhz

Here are the windows prof. 2k requirements:

You need 64 megs of RAM, and a 2 gig HD, but the chip should work.

I work with old dells for a day job. A pentium 1 will not do the job very well at all. I would recomend a p3 at minimum with 256MB of ram and a 4 gig HD. I'm not some psycho-gamer or anything, but I really think this is the minimum you will be happy with for w2k, or you can run winxp with this setup. Don't forget all the security issues you need to deal with.

If you can dig up a Dell optiplex gx110, you will be in hog-heaven. If necessary, spend a hundred and fifty bucks on e-bay to get one that is 'Maxed-out' with 512 RAM and a decent HD, you'll be happier in the long run; they are indestructable, the w123 240d of computers. Also, get a laser-mouse so you dont have to clean mouse-balls.

If you are worried about price, use linux. It is infinitely more secure, it is usually faster and it is free.

p.s did I mention linux was free?
