The Hardware Compatibility HowTo lists the SCSI cards supported by Linux.
The latest version (July 1996) is available at URL

A hub needs multiple Ethernet connections. I've seen Ethernet cards (NICs)
for PCs that have 4 ports, not the usual one, but I haven't seen one for
years. Using 2 Ethernet cards in one PC is possible, but it is definitely
doing it the hard way, considering how cheap real hubs are (4-port hubs cost
about $25 around here).
If you do put 2 NICs in one PC, you'll need to configure 2 interfaces (eth0
and eth1), use "cross-connect" cables to connect to the other 2 PCs (think
of these as the Ethernet equivalent of modem eliminator cables on serial
ports), and set up the Linux box to do IP forwarding so the other two PCs
can comminucate with each other (this probably means compiling a custom kernel).
People do something like this all the time, but usually not to save the cost
of a hub. This same general approach allows a Linux box to function as a
router or (with a bit more work) to let one "share" a single PPP connection
and single real IP address among all the hosts on a LAN. For more hints,
look at the relevant HowTos and mini HowTos -- Ethernet, IP Masquerading, IP
Aliasing, IP Subnetting, perhaps others (if they aren't on your system try
URL http://metalab.unc.edu/LDP/HOWTO/HOWTO-INDEX-3.html#ss3.1 for current
versions).
Hope this helps. Good luck.
