Using a ducky zero 2087 non backlit.  Bought from garage sales with an awesome price.  Just scour around from sellers.  The retail price is around rm269ish.

Filco Majestouch 2

While it is the quieter amongst mechanical keyboards, you'll be in for some noise upgrade as reds are quite noisy as well.
Far from it.
But it is very well built.

For me pretty simple advise for people wanting to get a new mechanical keyboard.

Filco Majestouch 2 if you don't need led lights.

Ducky if you need led lights.

Both are recommend over and over and over and over and over again you can't go wrong with either.

Of course if you have a specific model in mind you can ask for feedback but if you aren't sure what to go, just go with either 1 of above.

you need to know what you want on a keyboard
Crosair k70 RGB = RGB lighting but software very hard to configure(only cherry RGB switches in the market)
ducky shine =good quality and good lighting effect and its new so no 1 know what is the con or problem with the keyboard
filco= basic function but beast quality

All mech keyboard can change keycap just some keyboard dont have a standard layout so you need to buy extra modifier or get keycap set that have the layout you have
filco and ducky standard
razer logitech some CM storm and few others

Depends on what games you play.

Dota 2 or similar would be ok with blues.

Otherwise, I'd recommend Browns or light Topre.

Filco Majestouch 2 TKL

After so many days, finally see today you asking real question instead of continue spamming random questions. 

If you type more than actual gaming, you will need tactile switch like MX Brown.
The tactile bump on each actuation give you feedback to let you know you type the key or not.
It's very important for typing and touch-typing as well.
So, your recommendation is MX Brown.

Why not MX Blue (Clicky + Tactile)?
Because you buy to use in working place, clicky sounds are enjoyable only for owner.
But annoying for co-workers. So, MX Blue is out of the list.

Why Filco Majestouch 2 TKL and not Ducky Zero?
Because Filco Majestouch 2 (Made in Taiwan) is the best keyboard brand among all OEM MX Cherry keyboard.
Ya, it's the best in the world for OEM.
The unrivalled quality and offered best typing feel.
All quality, no gimmicks.
Meanwhile, Ducky Zero (Made in China) is just a step below the Filco.
Not forget to mention Filco uses costar stabilizers on those longer keys, better to press compared to Ducky Zero (cherry stabilizers).
You need to clip cherry stab to perform like costar.

In conclusion, Filco Majestouch 2 TKL MX Brown.
