With all due respect, you have the manual in front of you now
That is unless you started unplugging wires already, and didn't make notes, drawings, or take photos.
Let's use the Asus Essentio CM1630 motherboard for an example.
Couldn't find a CM1730, but that's OK. We'll use this one for a general example,http://www.ebay.com/itm/OEM-ASUS-ESSENTIO-CM1630-MOTHERBOARD-61-MIBBJ5-01-TESTED-/181007679725?pt=Motherboards&hash=item2a24e600ed
Put your mouse cursor in the middle. Now move your mouse around, using the Zoom In feature.
If this motherboard were mounted in a computer case, it would be turned 90 degrees to the Right.
Bear that in mind.
The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires from the Front Panel go to, is the Front Panel header.
Goes by many abbreviated names.
PNL 1, FP1, PANEL1, etc.
(Panel 1, Front Panel 1, Panel 1)
Go to the Top/Right corner of the motherboard photo. To the 6 Blue SATA connectors.
Immediately to the bottom of them, is a white Front Panel header.
Two rows of contact pins sticking up.
You need to make notes, drawings, photo, whatever; of where the wires from the Front Panel, go to each one of those pins.
(Some may not be used)
How to know which wires coming from the Front Panel, are the Power On switch wires, Power On LED light wires, HarDDrive activity LED light wires?
Remove the Front Panel from the computer. If it is Not just a cover, EASE it off just enough to look behind it.
You usually can follow the Harddrive activity LED wires.
Harddrive activity LED is usually AWAY from the Power On switch, and Power On LED light.
There's two wires down.
Now look at where the Power On LED light is. Can you see wires going straight to it?
Two more wires down.
From process of elimination, you now know the last two wires going to the Front Panel, are for the Power On switch.
(The Power On switch, is part of the plastic Power On Button assembly. If you look close at the Power On Button assembly, you can see this)
THAT sir, is the MAIN thing.
I can guide you where the other cables go, as far as power cables, and Harddrive cables, and Optical Drive cables. (CD/DVD drive)
If you have already disconnected the Front Panel wires to Front Panel header on motherboard; you get to play a game(?)
Power Supply plugged into power, use a small flat tipped screwdriver, and touch two pins at a time.
When you get to the two Power On switch wire pins, the Power Supply will come on.
Now it is a process of elimination.
Use an LED with two wires, to find out what the rest of the pins are.
The rest of the contact pins in the Front Panel header.
Grab the HDD LED light, or Power On LED light.
You're getting a new computer case anyway.
Touch two pins, and the LED light blinks?
That's the HarDDrive activity LED light, pins.
LED stays on?
That's the Power On LED light, pins.
Either of those LED's are dim, (When the Harddrive is active, or when the computer is on), switch the wires around.
You have the Positive ( + ) wire mixed up with the Ground ( - ) wire.
The 6 Blue SATA connectors on the motherboard:
If you look close you will see;
SATA0, SATA1, SATA2, SATA3, SATA4, and SATA5.
Or it may be,
SATA1, SATA2, SATA3, SATA4, SATA5, and SATA6.
The Harddrive plugs into SATA0 or SATA1.
Just depends on what the SATA connector numbering starts with.
The main optical drive, or a single optical drive; plugs into SATA1, or SATA2.
A secondary SATA optical drive will plug into SATA2 or SATA3.
(Look at the SATA numbering above, and you can compare side, by side )
HOWEVER, the beauty of SATA is; that you can plug whatever you want to, in ANY SATA connector on the motherboard; and BIOS will find it.
Plug the Harddrive into SATA 3? No problem.
Plug the optical drive into SATA 0? No problem.
BIOS will find the drive with the Operating System on it.
Then BIOS will know the other drive/s are optical drives.
(Make sure in the BIOS Setup utility, that the SATA connector on the motherboard you are using, is Enabled.
Otherwise BIOS will Not see the drive)
What cable from the Harddrive, and optical drive; plugs into those SATA connectors on the motherboard?
A SATA data cable,http://en.wikipedia.org/wiki/File:SATA_ports.jpg
Note the L-shaped opening in the SATA data cable connector.
Lines up with an L-shape on the motherboard connector.
One example of a SATA connector on the motherboard is shown.
This one is an Open design. Your SATA connectors on the motherboard, will be a Closed design.
Between a SATA data cable connector, and a SATA power cable connector, the SATA power cable connector is larger in width.
SATA data cable connector has 7-pins.
SATA power cable connector has 15-pins,http://www.playtool.com/pages/psuconnectors/connectors.html#sata
See the SATA harddrive example?
Note the L-shape is pointing DOWN. It is this way EVERY time.
Now you know which way to turn the SATA data cable's connector, when installing. 'Foot' of L-shape goes Down.
