Making my own case, where do I get a power switch?

Nothing really has the right form factor for what I'm trying to do. Anybody
know where I can get a power switch cheap? Radio Shack? Part Number?

Thanks!

You can use just about any momentary switch. They make thousands of
different kinds. I like the ones with LEDs or other lights in them :-) :-)
 
Great, I'll pick one of those up! Now does anybody know the voltage of the
power and hard drive activity lights?

Thanks!

They're LEDs; pretty much any standard one should work fine.

Like Jon says- any LED will do, with the exception of the super bright ones
which may draw too much current for your mobo. Being a diode, they have
polarity requirements but don't worry if you reverse the polarity, because
you won't damage anything. If you connect it backwards it simply won't light
up so in that case just reverse it.

and holders if you need them

Thanks for all the info!

Does anybody know where to get the connectors to connect these the switches
and LEDs to the motherboard? Maybe prewired?

Thanks!

At 5V a LED is toast. Are there resistors hidden in the line, maybe the
cabling?

You are correct. I just measured with a voltmeter and
it's 3.3V. My apologies.
 
No, my apologies, I thought is was 1.7 to 2.2 volts, the normal LED voltage
range. Are you measuring the voltage under load, albeit very small.

Without the LED attached, the voltage is 3.3V. With the LED
attached under load it 2.0V.

It's current limited though, the limiting resistor being on the device
which the LED connects (usually the mobo).
