Hi all:

I'm working on putting together my first system. Almost done, with
considerable help from those on this forum. Many thanks.

One final question:

The Power LED connector from the case needs to be plugged into the
jumpers on the mainboard. However, the two "prongs" (sorry, can't
think of a better word, though I'm sure there's a standard)

Usually called "pins". Same thing.

on the
mainboard are adjacent, whereas the wire from the case is 3-wide,
with a gap in the middle. Here's roughly what I'm talking about:

| ______
|-- | * |----------
|-- | * |
| |_*__|----------

Question is, can I just pull the wire out of the 3rd position on the
connector and push it into the middle one, and then plug the whole
thing into the mainboard? What's the right way to do this?

One of the 3 connectors if for the RPM sensing of the fan. If you don't
need RPM sensing, you don't need 3 wires. But you do have to make sure the
2 wires that get connected are the power wires, and you should note the
polarity. If you get the polarity wrong, the fan will spin backward.
That's OK if you can flip the fan around, but it won't work if the fan can
only go in one way.
