1) You could get a much smaller SFX PSU if you want, but your current PSU is not limiting to a blower style card. A non-blower card with one of its fans obstructed by the PSU being too close to it is still a quieter and cooler card than a blower under load.
- You can also have the fan of the PSU pointing inwards and that way it is sucking out the hot air from the GPU and is less of an obstruction.
- PSU don't degrade without use, and without rough use what degrades is the fan.
2)Yes, that is newest type of board you could buy for Ryzen.
3) The box cooler does the job, but it is not that great. However that low profile Noctua is not an ideal upgrade for the price and for the situation because you can fit a better performing and bigger tower cooler of similar price like the
ARCTIC Freezer 34 eSports DUO in the Nano S.
4) Not worth it for the price, unless there is a deal. with 3600x you get a CPU that is better binned, and a better cooler on the box, but not better than a one you can buy on your own.
5) Two situations:
- Keeping it nvidia: Asus GPUs are sometimes a bit more expensive than other brands, even keeping to 2070 super you can find non-blower cards from the other brands like a Gigabyte WINDFORCE OC 3X that are cheaper than the blower Asus. I think getting a card with 3 fans also further improves the situation with your PSU being too close to the GPU. You case allows for cards that up to 31.5 cm long which is longer than most cards nowadays.
- Getting a RX 5700XT is paying considerably less for similar performance to the 2070 Super, but it depends on whether you are used to the Nvidia ecosystem and prefer its perks or not. Same as above, a longer card with three fans like Gigabyte's is what I would recommend.
6) Sometimes depends on the quality of your TV, since cheap TVs may cut corners on the quality of the scaling, but 1440p definitely looks fine on 4k TVs, especially if you are not sitting as close to it as if your were using a monitor.
7) Lack of motherboard fan headers aren't a big issue. For those situations there are
cable splitters, or
fan hubs that get extra power from the PSU.
8) The Crucial MX500 is a SATA drive with an M.2 connection, I would say as boot drive get an NVMe drive because there are models
that are about the same price for the same storage.
