Supermicro. We have very limited selection of stuff here in Canada in general, it sucks. In fact it's worse now that we lost Tigerdiret and NCIX as they were really the only ones that even had server stuff. My next builds will be whitebox as it's really the only option now. Ebay is too expensive because of shipping.
It's crossed my mind to open a business just so I can get access to suppliers like Ingram micro as they tend to have larger selection. They tend to have minimum order amounts per year though.
