The "mini-tower" here lists 410W. You have a 600W supply, so I guess the
supply has been changed ? I would think, based on the motherboard description
in the Precision workstation 420 (dual Pentium III, 840, rambus), that
it would have been highly unlikely to have a 24 pin main power connector.
And an old computer like that, probably would not have had a 2x2 ATX12V
power connector either. (Introduced in P4 era.)

OK, there is a picture here of the old motherboard. I downloaded one of the pictures,
adjusted contrast and brightness in Photoshop, and I count a 2x12 connector
and a 2x8 connector. So if you really have the old power supply in there,
chances are, the connectors are not the right type. Back in the days of
things like the P3, a 20 pin main connector would have been the standard,
so it isn't likely, if they used a 24, that it has the same pinout as
today's 24 pinner.

If you want a spec for a 24 pin power supply, the kind you might use with
the M61P-S3, you'd look here. Compare the wire color listed on page 37
for the 24 pin connector, against the connector you are using. While
your photo matches the colors, for half of the connector, I cannot see
the other half.

These are previous generations of ATX standards, for reference if you need them.
The last one, the 1.1 version, is from the days when -5V was on the main connector.

I can see a Lead Power 600W here, and this looks like a more recent supply.
The connectors look like they'd work better with the M61P-S3.

Based on the picture, I see that your "20+4" connector is slightly askew.
The 4 pin part looks seated, but not the 20 pin part.
OK, since the board is 12" x 8.6", the holes on the right edge of the
motherboard would be missing. And you're right, the connector, since it
is right out near the edge, is unsupported and flapping in the breeze.
All you have to do, is place the right sized object underneath the edge of the
motherboard, to give it support. If you have some spare standoffs, put
them under there. I'd probably find a scrap of wood of the right
thickness, to stick underneath there. Then you should be able to
finish seating the 20 pin portion of the 20+4.
When you're finished, the "ATX_12V" connector shown in the manual, should
have a 2x2 connector, with two yellow wires and two black wires, plugged
into it. The main connector is 24 pins, and you can verify the wire colors
against the ATX 2.2 spec above (page 37).
Don't turn the power on, until you've verified everything is in order
