Making a NAOMI PSU from a standard ATX PSU

I have one for sale in bundle with a GD-ROM power harness:
(it plugs into one of the 4-pin peripheral power cables of the ATX power supply)
PM me if you want them.
It looks like in that pic, your gd-rom connector goes 12v, NC, 5v, 5v, G, G.
According to the starter faq, it looks like it should go 12, NC, 5, NC, G G.
Which one is correct? I'm expecting most of my parts to arrive this week and I'd like to get it right the first time.

Any help would be appreciated!
Should be
1 = +12v
2 = NC (or +12V)
3 = +5v
4 = NC (or +5V)
5 = GND
6 = GND
I've seem some with pins 2 and 4 wired, some without, doesn't seem to matter.
Probably wise not to wire up pin 2 or 4 as all the ones I've seen recently are not wired.

Oh I know what, I guess I worded my question wrong. I was either planning on just powering the GD-ROM from the ATX supply, or powering both the motherboard and GD-ROM from the ATX supply. I know already the Capcom I/O won't handle both. If I were doing both, I was just going to add pins on the female side of the ATX motherboard plug in the cab to output to NAOMI, otherwise just use the 4-pin HDD/CD one. I guess it doesn't matter, it'd probably be best doing the latter to save trouble.
I plan on doing a little mini-faq on the ATX conversion, going through where/what to get, how to measure your voltages, getting your pinouts right, etc etc. Assuming my parts from the geezer stop partying in New York(they have them for like a week now, I hate USPS), and i don't get delayed in Dublin, I'll be doing the work this weekend.
Anyone think that would be useful? If so, would anyone be willing to proof it once I'm done?
Thanks
