A few nights ago I built an AMD based FreeBSD box that people might be
interested in. It is based upon the Biostar MB-8433UUD motherboard and
AMD 5x86-133 processor. The motherboard and processor together were $200
from a local computer store, although I've seen the same combo for $167
in Computer Shopper.
The motherboard features 256K L2 cache, three PCI slots, four ISA slots
and a ZIF socket. It will take 128MB although we have only 16MB
installed. The motherboard already has an IDE controller and parallel and
serial ports (16550), so you don't have to buy a seperate controller. It
features Award BIOS.
If you have a spare case sitting around and need another machine, this
may be the way to go. I stuck it in an old Zeos case that a friend had,
as well as the IDE spare drives I had hanging around. (you bought them,
might as well use 'em)

Right now the machine (t-rex.tioga.com) is my ftp server and cu-seeme
reflector (the BSDI binary). I might build another machine similar to
this one for a pop box, scsi of course.
The above benchmarks are at ftp.nosc.mil in /pub/aburto
So, for $200 or less and spare parts, you can have a decent machine. If
you have seen these benchmarks already I apologize, but if not, then I
hope this information comes in useful.
