¿QUESTION? PC Power Supply?
Hold your danged horses! This ain't what you think it is! Are PC power supplies 12-volt output? They are small reliable and cheap. Don'f know about the connection friendliness. Sorry about the...

Oh well the Cheapos will work.
It's difficult finding a 120vac / 36-vdc converter that is very inexpensive. For LED lighting.
If you don't need isolation from the line voltage, I think you could in theory wire up a 48V transformer as an autotransformer (connecting the primary and secondary in series with the proper polarity) that should be relatively close to 36V rms nominal output. Add a bridge rectifier and a filter capacitor for a super simple unregulated linear power supply, and a little fiddling with the loading and maybe some current limiting or voltage dropping should get you something that's adequate. You would need to derate the output current of the 48V transformer...by about 30% if I'm doing my math properly (since the secondary winding now carries both the input and output current).
