Odd power supply

Hello,
looking to replace a psu that came originally with a mini case (squarish shape) but run into trouble finding a replacement on newegg.
the issue is size and shape required for fitting the psu into this case.
here is a pic from newegg of what it looks like as far as fan and receptical orientation:

the bolt pattern i need is square. the depth is about 4" as opposed to a 6" depth, and the cords coming out of the unit i have to replace exit from the bottom and not from the back as most power supplies.

it requires a four pin for the cpu on the mainboard, sata as well.  
any ideas on what to search for? where to find it?

thanks
