Replacing HP p6142p mobo with new ASUS mobo

Have HP p6142p workstation.  Purchased new ASUS mobo (M4A785-M) when HP one up-and-died.  Upgrade went perfectly until last connection - front panel power/reset/LEDs to mobo.  Old mobo (ASUS/Pegatron #M2N78-LA) used 2-row, 9-pin connector (2 rows of 5 - 1 empty) whereas new one uses ASUS "Q Connector" - a 2 row, 12-pin connector (2 rows of 10 - 8 empty) having completely different pin assignments (see embedded image below).  Based on the # of posts on the net, this appears to be a somewhat common problem yet I cannot find what I consider to be a good solution!

Some have suggested carefully removing each socket from the original connector and plugging into the motherboard where appropriate while others recommend cutting off existing connector and building one or more sets of new smaller connectors.  Unfortunately, both of these approaches have drawbacks...

The first approach is problematic as repeated attempts to release the sockets from their housing have proved troublesome, at best.  Once freed, I will have several discrete, uninsulated sockets that are unlabeled.  I suppose I could group like wires together and sleeve them but this seems like more work than should be necessary.

The other approach should yield a somewhat more elegant result but finding the correct Molex connectors, of the right size and pitch, has also proved difficult.

Does anyone know of:

1

An adapter that has been fabricated to mate these two dissimilar connectors                         or

2

A better way to quickly achieve the result I'm looking for (a robust and reliable connection between the two interfaces without it being a "kludge")?
Thanks in advance for any-and-all suggestions!

About the easiest way is to find an old case with some of the small 2, 3, and 4 pin connectors .
A straight pin usually will 'trip the clip' so you can slide the black plastic covers off the old wires and then put the wires in your case, into them.

It looks like you will need:
- two 2 pin covers -- 1 for the IDE LED and 1 for the Power Button.
- one 3 pin -- for the PLED.
- one 4 pin -- for the speaker (if needed).
