Building my first SFFPC, need advice on the parts I've selected/need to select.

Build Help/Ready:

What is your intended use for this build? The more details the better.

What is your budget (ballpark is okay)?

No specific overall budget, but I'm looking to minimize costs for the parts that aren't locked in yet.

In what country are you purchasing your parts?

India

Post a draft of your potential build here (specific parts please). Consider formatting your parts list. Don't ask to be spoonfed a build (read the rules!).

Provide any additional details you wish below.

1) CPU/GPU/MB choices are fixed, due to case and part availability issues. SSD is already purchased.

2) My case has a 47mm CPU fan height limit. A more expensive alternative is the NH-L9A with extra foam edges, is that beneficial for heat/sound reduction?

3) The PSU in question comes from this amazon link. Based on the PSU Tier list that was recently posted on /r/pcmasterrace, I believe this is an "A" rated model.

Wiring is very tight since this is an SFF build. Is the Corsair SF750 worth hunting for? Do I need an even bigger PSU than any of these?

4) RAM selection is boggling my mind, sidebar's selection resources doesn't have anything on that. I'm looking to get 32GB. Any suggestions?

Thanks for the help!
