This is a good idea about just tossing the hard drive. You could also
write a bootable CDR and just use that.
I would be very careful about running a CPU without a fan. IIRC, you
said you were using a Pentium 166. With a good heatsink and enough
airflow past the heatsink you could do without a fan. Newer CPUs
cannot run without a fan; AMD specifically recommends that you never
power on an Athlon without a heatsink and fan, not even for a couple
of seconds just to make sure it works.
