The light bulbs maybe, but you also run things much higher than 350
watts from time to time. The hair drier is meaningless.
Most of the lights I leave on now are LED pulling 10 or less watts. The
entire population of light bulbs in my house left on now doesn't get to
100w anymore.
I have 2 dell 2950's that pull a large power bill. That is near your
345 watts each, and I am plotting to take them out and their
replacements are Intel NUC's @ 40w each, pretty much the same go power.
the 11/93 probably isn't running as much compute power as one core of
the 2950. Nor possibly a Raspberry Pi. Whatever you want to do to
convert $$ to radiant heat, I guess no one is stopping you. Running the
old stuff for fun even for extended periods is one thing, but a BBS has
possibly the mission to stay up. Depending on what the OP has in mind.
thanks
