Can't find any info on the RF 118uc mobo. Is there a brand name on the mini tower? Any other names anywhere? Is the mini tower fairly new? Most psu'a are compatible with mobos.

Found it. The puter is an HP Compaq DC7600. It is a business computer and the power supply in it is 240 watts with 2 sata, 1 pata and 1 fdd connectors. Why would you want to put that much power into this unit? Seems like overkill. Take the cover off and see if they are physically the same size. If they are the same size you could swap them. You can see it here at http://h20000.www2.hp.com/bizsupport...&lang=en&cc=us and at http://h18007.www1.hp.com/products/q...12253_div.HTML
