[clue-tech] Suggestion for upcoming presentation - build you own PC

[Dennis J Perkins]

I've always built my own desktop machines and I enjoy it, even if I need
to do some research on new developments.  They might cost more but I
have exactly what I want in my system.  Any compromises are mine, not
the manufacturer's.  Well, that's not exactly true... the manufacturer
might have compromised on capacitors or noise, etc.  Still, there are
less compromises.

I think you can build a good system for anywhere between $650-$1100.
The spread is due to the fact that there is usually something (usually
more than one) that you just want to have.
