Eurocom is in Canada, and they make some of the most outrageously powerful laptops ever. I have one that weighs 12 lbs, has 12 GB of RAM, 1 SSD, 2 HDDs in RAID 0, and an i7-980X desktop processor.
Note, they will screw you on price unless you call them up and jew them down. Good hardware, several choices.
For myself, I wouldn't hesitate....but I simply can not bring myself to ordering an off-brand for a client.
I wouldn't call it an off-brand - it's based on the Clevo platforms, which are rebranded to Sager, Eurocom, AvaDirect, and several others. Build quality is on par with the best of Lenovo's workhorses.
If you want something mainstream, Dell's Alienware lineup is pretty awesome too.
