Many apologies to Ian and FemmeFatale for not responding sooner. I already knew it wasn't the case fan. I know where its leads are. I found out by Googling that power supplies _usually_ have an internal connection, and thus don't have a connector coming _out_ of the power supply box to plug into the motherboard. Apparently Abit's manual is indicating where to plug in an _external_ connector from the power box _if_ one exists, but doesn't indicate that there usually isn't one. But their manual is generally excellent and comprehensive, so I might just send them a heads-up on this particular detail. The motherboard, by the way, turned out to be defective. All I could get on bootup was "checksum error - defaults loaded", and no keyboard response to enable me to go into the bios to try to fix it. Abit has okayed an exchange for another one. When I get it I'll know not to worry about the powerfan connector. Thanks to both of you for your responses.
