Modifying a Computer PS

Is it not too difficult to modify a computer SMPS? Can one just replace the
heatsink, transistors, and inductors wtihout worrying about anything else? I
assume they have current limiters in the device that would need to be
modified too? (or disabled and simply use a fuse?) I have an old ps that is
raded for 12A at +12 and I'd like to get that higher.

Or is it possible to run the devices in parallel without to much
modification?


Thanks,
Jon

There are articles out there on how to modify SMPS - IIRC
http://www.siliconchip.com.au/ had one.

No.

Depends entirely what you want to do.

I modified a PSU into a variable 5-12V (instead of constant +12V) without
much hassle.

Look at www.4hv.org in the "General Science and Electronics" forum, a
