Dell proprietary power supply wiring

I'm looking to rewire a standard atx power supply so that is compatible with an old motherboard (Optiplex G1). I've got the old power supply that i will be replacing, so i will cut the old connector off and solder it on to the new one. What i want to know is the wiring of the dell psu in comparison with the new atx one, so i know which wire to solder where...

Any ideas, or links to websites?

Is it a DELL GX1 or GX100?
visit support.dell.com which has all the information about the PSU information on latest models.
An adapter is a better idea, but if you want to do your own wiring:

I agree that the adapter would be preferable, but I'm in the UK, and no one seems to sell them here :(

I've got an atx pinout diagram too http://xtronics.com/reference/atx_pinout.htm 

but i'm a bit confused by which pin should go to which - a standard atx connector is 20pin, the dell is 26. I realise that the majority are taken from the 5 volt rail etc, so can these pins be simply wired together?
Here's another article: http://www.informit.com/articles/article.asp?p=31105&seqNum=4

Dell remapped the wires, and you have to figure out what goes where.  Wiring similar pins together is not advisable, because of the current draw and the size of  the wires.
