I've checked the PSU under load and the voltages are fine , I imagine that it would be very easy to put a 230w atx psu inside the unit ( I muck around with power supplies at work. )
I have a sneaky feeling that the unit isn't all that it seems , it's too much like the advert when I bought my non-working unit , it just all sounds familiar.
Your very lucky to get snaps donated to you ! I have to buy all my toys from places like eBay , sometimes you win ( got a 1100 for $76 , upgraded to a 320gig hdd ) and sometimes you don't .
If you do find a 4000 mobo I'd be happy to give you a reasonable amount for one .
What are the 6 cable PSU to converter connector that you talk of , I could probably knock one or 2 up quite easily depending on if the connector is weird or not.
Oh about this life thing you think I have , I don't have one can anyone point me to where I can download one or can I have a copy of someone elses ???
