[talk] Used parts outlet?

[Beeblebrox]

Hello everyone.
Just moved back to NYC area after living for two decades in Europe.
I brought my MoBo & HDDs with me, but there was no point of lugging the case and power unit over the ocean.
I found a 550w Power Sup on Amazon for about $17, but the case is a problem as I'd prefer to buy a used one for 15-20 bucks.

Anyone have an old ATX compatible box laying around or maybe point me to a decent second hand electronics outfit?
Thanks & Regards.
