hey i'm looking for a 100-500ohm variable resistor. any ideas where i could find one? found a couple on the internet, but i'd prefer to pick one up locally or from a reputable online dealer. loc: burnaby, bc
background:
i just bought a xeon x3210 and gigabyte 650i sli board. i was too cheap (damn school...) to buy a 680i board, so i'm stuck without the GTLRef option in the bios. which means my board dont oc worth crap. i can barely get it stable at 2.4ghz

so i wanna solder the resistor to my mobo to allow me to manually adjust the voltage.
cheers
