so my keyboard is 6KRO . how do i change it to NKRO ?

or it cant be done .....

I'm using cherry mx brown right now.

Anything harder i will definitely not like. In fact more lighter without tactile would be even better for me :}

Cherry mx red ?? 

Any keyboards that allow the user to remove/detach the keys in one go for easy cleaning? Been using the generic/cheap keyboards so far, would like to get a much decent one but just wondering if there's such a type of keyboard or not.

BTW, to those who want to buy Razer BW, i had yet found another flaw on it(should be many unit also face such problem). Keys among the same row having different height. For example, my ''N'' seems to be sank by 1mm more compared to ''B'' and ''M'' beside it(i mean when it is not pressed and the different remain also when pressed down). My ''C'' is elevated higher than other keys(same row). Luckily, those keys' switch feel and sound still consistent...

I start to doubt about the so called ''superiority'' of Mechanical Keyboard over rubber dome after found out so much flaws on it...
