If you haven't gotten a hold of a case:

NCIX.com - Buy Coolermaster Elite 370 Black Mid Tower ATX Case 3X5.25 1X3.5 5X3.5INT No PS - COOLERMASTER - RC-370-KKN1 - in Canada

That's the lowest I've seen that case at so far, great value, good quality, decent aesthetics.

Lot's of free shipping promos at NCIX's sale this week too. If you can fit it in your budget: NCIX.com - Buy MSI GeForce GTX 560 Ti Twin Frozr OC 880MHZ 1GB GDDR5 Dual DVI Mini-HDMI DX11 PCI-E Video Card - MSI/MicroStar - N560GTX-TI Twin Frozr II/OC - in Canada
I would consider going with an AMD quad core or Intel i3 dual core with 4 threads to squeeze out some budget room if you want to go with that GPU.

NCIX.com - Buy NCIX Gaming Bundle Deal Gigabyte GA-P55A-UD3 P55 CrossFireX Motherboard & Intel Core i5 760 - Bundle Deals - GA-P55A-UD3 & Core i5 760 - in Canada
Decent bundle, free shipping for your order.
