Pinout (Wiring diagram) for the GigaByte GA-8I865GVME motherboard's Front Panel header,
(Looks like a 1 but it is an 'Eye'. GA-8 i 865GVME ),
{The plastic front of your computer is the Front Panel.
The area of pins on the motherboard, that the Front Panel cables (Wires) connect to, is the Front Panel header }
;Motherboard Manual download page,
http://www.gigabyte.com/products/product-page.aspx?pid=1933&dl=1#manualLook under the heading - English
Look across from English, and click on the country name nearest yours.
This is a PDF file. After you click on the server country it may take 30 seconds or more, to see the first page come up.
It may also take additional time for the file to fully download.
(Took approximately 30 seconds just now for me. Medium speed DSL connection)
At the top of the PDF file is the page number box. It is to the right of the Down Arrow.
Go to Page 6.
Processor to the top, Ram Memory slots to the right, the Front Panel header is at the bottom right corner.
(F_PANEL)
It is two rows of pins that are laid out horizontally. It is parallel to the bottom outside edge of the motherboard.
Go to Page 22.
F_PANEL (Front Panel Jumper)
The pins are numbered Even on the top, and Odd on the bottom.
Starting at the Left side of the motherboard going to the Right, for the TOP row of pins;
Pins 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20
Starting at the Left side of the motherboard going to the Right, for the BOTTOM row of pins;
Pins 1, 3, 5, 7, 9, 11, 13, 15, 17, and 19
A) Pins 2 and 4 are for the Power On LED light. (On the computer case. Not on the motherboard)
(Pin 2 is for the Positive { + } wire.
If the LED light is dim, switch the wires around )
B) Pins 6 and 8 are for the Power On switch. (Plastic - Power On button assembly has the Power On switch inside it)
C) Pins 10 and 12 are not used. In fact there probably isn't any pins.
D) Pins 14, 16, 18, and 20 are used for an internal 'speaker'. The 'speaker' is used so you can hear any BIOS Error Codes. (The computers way of telling you something is wrong, and an area to look into for it)
E) Pins 1 and 3 are for the HarDDrive activity LED light.
The LED light that blinks when the harddrive is active in use.
(Pin 1 is for the Positive wire)
F) Pins 5 and 7 are for a Reset switch, IF USED.
G) Pin 9 is NC. Not Connected
To Add:
1) If the Dell Dimension 4600 power on LED light has 3 wires, it is a dual color LED.
Only use two of the wires, and one color.
(Follow the wires to the LED light. One is a Ground wire { - }, and the other two are positive wires for the dual colors of the LED )
2) The Front USB headers are on Page 24
Make sure your Power Supply has a 4-pin ATX +12 volt power cable. Plugs into the square connector on the motherboard, to the bottom Left corner of the Processor socket.
It is power for the Processor.

For a time period Dell was really @nal about being a Proprietary computer manufacturer.
This means they wanted THEIR parts used in THEIR computers.
I don't know if your Dimension 4600 falls into this category, or not.
They switched the pins around in the ATX main power cable connector, on the motherboard.
Go to Page 18.
Look at the connector that has 20 socket holes. (Two columns of 10 socket holes)
The Dell Dimension 4600 also has a 20-pin ATX main power cable connector, on the motherboard,
http://support.dell.com/support/edocs/systems/dim4600/en/4600i/sm/techov.htm#1138239Scroll the page down a little, look at the illustration for the DC Power Connector P1
See how the power and color of the wires are labeled for each pin in the connector?
Orient the connector by the lock tab on the side of it. Now compare the color chart here for the wires in a standard 20-pin ATX main power cable,
http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20A) Orange colored wires are 3.3 Volts
B) Red wires are 5 Volts
C) Yellow wires are 12 Volts
D) ALL Black wires are Ground wires
(ALL are DC voltage)
Guess what would happen if a 12 volt wire is connected to a pin that uses 3.3 Volts, or 5 Volts?
Yep, lets the 'Smoke' out of the motherboard.
Guess what would happen if a 3.3 , 5, or 12 volt wire is plugged into a pin that is a Ground wire?
Same thing. Will fry the motherboard. Possibly the Processor, Ram Memory, Harddrive, and so on, also.
Check before you plug in, and turn the computer on.
For additional questions, or to clarify anything I have stated, please post in a Comment.

Without knowing what motherboard you have, it's impossible to say.
The picture below helped me figure it out.
