The led's I am going to use are around 3.5v, with about 30mA. I think the voltage equation that was given on a tutorial calculated the resistor to be around 200-400ohms.

im using 3.3V LED's on my mod, with a 1V tolorance, and the mobo supplies 3.35 (Tested it) so i don't need a resister, generally if you match the LED voltage to the source voltage your cool, you only need resisters when a clean power supply is needed, lower current or lower voltage.
and looking good mate.
Gotcha. Thanks!
nice start man
Finally got a mobo, my girlfriend helped me and found a sweet one at Fry's Electronics.
Okay, got a dilema....I have my psu plugged into the motherboard and i have the power switch, both front led's, and the reset plugged into the mobo. I plugged the psu into the outlet and switched the psu on and nothing. Not even the led's lit up. Should i have a little more patience and wait till' have everything hooked up? or is my psu faulty?
The only LEDs that should turn on if you haven't crossed the power switch yet if possibly a status light on the MBB. Try crossing the MBB power switch and see if stuff powers up. Oh also, I just realized you didn't specify this...the CPU is on the MBB, right?
No, i do not have a CPU on the mobo right now.
There's your problem. Nothing's gonna happen until you have the CPU, HS/F, and RAM on there.
yea, the mobo checks for cpu, ram and gfx, it will start without mem and gfx, but will post an error, but with no cpu it will do jack (You know the rest)
