CoolerMaster's Silencio case range and fans are very quiet, Fractal have a good reputation too with their R5 model.
Crucial's SSD's seem to be the current flavour of choice, storage wise, 250gb is better for the OS with a storage hdd, I only mention the WD Green because my own is silent in my old HTPC, others perform better but add noise and cost.
For a single card you will not need more than 550w, but the Superflowers fans I have read can be noisy when they start spinning, if noise in that department is an issue, then your looking at a lot more for a fanless model.
That said, I have a Seasonix X series that is silent and rarely does the fan spin when under load, and my old Corsair HX-450 was pretty quiet when the HTPC was idle.
I doubt you will have an issue with PSU noise though. Especially with a CM case designed for quiet operation.
Noctua coolers should need no explaining, one of the best if not the best customer service CPU cooler producers, they are a joy to fit and really are quality, and quiet too.
Now gaming wise, well currently the 290X is one of the best cards going for the money, and MSI's GPU cooling gets good reviews. But if this is a mid range system, and your using a TV, you can get away with less.
This is just an idea of a decent 1080p gaming system with quiet components though.

But you could posibly go smaller. If you do not need a Optical drive you have a few nice case options. For anything running a passive PSU and passive GPU though, I would look for a small case with good airflow. If quiet is important, then no overclocking is worth considering, and a non overclocking CPU becomes viable.
