It depends on you what you want to do, but I love messing around with computers and would find this as a chance to work on something that if it all goes pearshape you have lost nothing but you may gain some knowledge .
I would go out and buy a CHEAP GENERIC power supply and put it in, if it works thats terrific you have your computer back.
If it doesn't you have only lost a few dollars (you can save the power supply as a spare test one.
