The main problem is memory. You need at least 12-16 MB to run X on
the client. This usually means 4 MB 30 pin SIMMs and they are hard
to come by these days. A 486 is desirable, but a 386 will pass muster.
I have a couple of donated 486s you can have.
On the server you should have a midrange Pentium and beef up the memory,
say 8-16 MB extra per client, because the apps run there in the X-terminal
case.

I'd say 10-20 should be no problem. The X protocol isn't that hard on
the LAN. It's not like VNC which copies (compressed) bitmaps of screen
regions. For example when an xterm scrolls, the client tells the X server
to move all but the first line up, and then write some characters on the
new line, which doesn't involve copying the bitmaps for the characters
but a render text directive, which will load and cache the font used.
It's only when you try to do things like remote xanim that you call
XPutImage often.

You can buy Netmaster 10/100 Tulip clones (MX 98715 chip) at computer
markets for $25-30. Cheap 100 Mb hubs start at about $180, better ones
will cost you more. But 10 Mb may be perfectly adequate.
