converting dell power supply need help

I searched and read and searched and read all night but could not come up with anything on my specific needs.

I have an old dell 4550 desktop computer, the power supply model number is NPS:-250KB B. I am just wondering if this is a useable power supply or if anyone knows anythign about tinkering with this paticular one?

Where do I start?

There should be a label on the supply showing the output Amps at 12V. A quick search on ebay

shows that it will do 14A.

If you want a good, powerful power supply (42A or 47A), check my blog. I am local so you can come by and pick one up for $40.
