I can type very quickly on my Blues (much faster than I could ever compose tbh) but they're very loud and the high actuation force means that typing is more fatiguing. My favourite is Browns but it also depends what Browns. The Corsair MX Browns feel like a Red with dirt in them - just horrible.
 
In the end keyboards are entirely subjective. Some people love Blues and never want to use anything else and others prefer just a membrane. I'm currently using a low-profile Brown board and it's great, for me. Try some out if you can.

I have a blue keyboard (Red Dragon).  The keys were too loud at first, but I got used to it.  If I was buying again, I would have gone for a quieter keyboard.  That being said I do like my keyboard's build quality and some of its features (volume wheel, macro keys, RGB options, etc).  Probably your best bet would be to stop by a Best Buy and try some of their display keyboards to feel and hear different types of key switches.

While I've only ever owned Cherry MX Brown keyboards with rubber o-ring dampeners, I have used both MX Red and MX Blue keyboards for extended periods of time in the past, either at friends' places or when I used to sell this stuff in a retail store.
MX Blues are straight up not for me, as they're far too noisy and feel very aggressive when I'm using them - I do see the appeal though for those who enjoy an "angry" sound when fragging noobs in online games. MX Reds are nice and quiet, but have no tactile feedback when actuating, creating a very disconnected feeling when I use them for extended periods of typing. (I do web design & some light development as well.) MX Browns are my favorite because they feel like more beefy versions of rubber dome / membrane keys, but have better consistency and longevity over extended periods of typing, all without making a racket.  
However, as @Slottr noted, the only person who can really tell you what works best is you, so I would recommend seeing if a local shop will let you try a few display models (assuming you have local shops open right now, given the pandemic) or pickup a Cherry MX sampler like one of the ones linked below.

Hi I'm new with mechanical keyboard,
 
I'm a web developer / gamer (if time permits =)
 
Was wondering about blue / red / or even brown switch. I do hear that blue-switch is clicky and loud. I haven't really tried any of these switches personally.
I wanted to get the red-switch, since it will be quiet vs the blue. But I'm hesitant, as i might miss out the point of mech keyboard? I do hear that blue-switch does give a good overall experience in terms of satisfaction when typing.
 
My thoughts actually are
RED - so it won't be too loud, specially when doing conference call OR kids sleeping in the office (they sometimes do =)
BUT will i miss out if i go for red? 
 
A feedback from guys who really used and own both will be greatly appreciated.
 
My current keyboard by the way  (k350)  had it since 2010 Hahahah

Your 5700 XT has 5v addressable LEDs while the headers on your motherboard only support 12v standard LEDs so unfortunately it won't work.

You'll find that SSDs and case fans don't take up much power at all.

That's all good ?
More than plenty wattage (100W CPU, 200W GPU, all the other stuff is like 100W combined) and that's also a good quality PSU.

750w is plenty for the average build, which yours seems to be.

It's overkill to a degree...you got nothing to worry about.
