Mini PCs have quietly become good enough to replace a full tower for most non-gaming households, and under $800 CAD there are now genuinely capable options rather than the underpowered budget boxes of a few years ago. The trade-off is limited internal upgrade room and, on the cheapest models, weaker thermal headroom under sustained load.
In this price range, the meaningful differences are the processor generation, whether RAM and storage are soldered or upgradeable, and port selection — especially the number and type of display outputs if you plan to run more than one monitor. Integrated graphics have improved enough for light gaming and media work but still fall well short of even a modest dedicated GPU.
Below are sensible picks at different points under $800 CAD, what to check before ordering, and the questions Canadian buyers ask most often.
