Has anyone come across any sane ways to reconfigure an SMPS? There are a ton of ex computer ones out there - it'd be interesting to rework one to generate +12 V say.

I'm fairly certain that my name change to Genome Smith is going to give me a better chance of fondling her melons than dicking around with old bits of computer s*it.
Obviously she will then make huge sexual demands upon my body and become totally satisfied and my bed will get a big soggy patch as we move about.
Then I will spend the rest of the night with a sticky bum listening to her snoring.
Sounds like a s*it deal to me......

Well, you could put a 5 ohm, 10 watt resistor for a dummy load on the +5, and just use the +12V that's already there.
Good Luck! Rich
Ideally I'd like to up the amps on the 12 VDC supply, perhaps add a 24 VDC output.

It is possible. I modified an old AT PSU to deliver +/- 24V and +/-10V to power a sub-woofer. Only 24V is regulated, the other voltage may vary a bit depending on the load (which is nice, because the fan is now also running faster when the load is higher).
I un-tangled the common connection on the transformer and re-arranged the windings.

That is good to know. Computer SMPS are very available.
