Push pins for mounting heatsinks on mobos?

[firefly]

Does anyone know where I can buy sprung push pins for attaching a heatsink heatpipe array (northbirdge, southbridge, vrms etc) on to a mobo?

I'm missing a few on an MSI mobo - the heatsink heatpipe array is attached but missing a few pins.

I've seen them at PC-World. They come in a heatsink kit tho, you either get two or four in the pack.

Try Maplins.

Try kustoms.

If all else fails ebay...
