Theres a few good cases out there with a focus on noise reduction. Most will have an option for a solid or windowed version.
As for CPU coolers, if you just want quiet without being used for overclocking, you could grab most any tower cooler and they're be near silent in any of the cases I've listed below. Any of the coolers I'll suggest will fit in the cases and allow for any sized RAM you might want.
I couldn't find any sources for these coolers in Canada's partpicker but they would be worth looking for or shipping from the US.
Coolers:
