Where can I get a capacitor?? I screwed one up on a motherboard I just got :(

[ElDiablo]

I was putting together an athlon system with the ECS motherboard for my uncle when i accidentally jabbed one of the capacitors with a cd-rom drive. Now the system is totally unstable and I need to get a replacement capacitor to solder on. It's a 1500 uF 6.3v and radio shack apparantly doesn't carry them.

Does anyone know where I can get one??

Thanks,

Drew
