well i had quick look but all i get up is all the chav car bits. is it the 3mm ones i should be looking for? also the brighter the better i guess. theres ones with free resistors on there, will i need them?

If you are replacing them, then buy the same size. It just refers to the diameter of the LED. The resistor is for running them off 12V. As leds are roughly 3.5v each.

OK standard leds ae 5mm

You don't need a resistor if you plug them into the motherboard header (power and hdd) as that is around 3V but you'll need a resistor if you connect to the 12V from the psu.

I found that blue tack makes a good alternative to soldering lol

Mini Terminal Blocks are another good way to connect LEDs

they all so come under the name Chocolate Blocks
