@Sir Ahsan
I think a guy who would spend 4,500 on gaming headset would mind spending 5,000 on gaming keyboard. Even the midrange system should have something like A4Tech X7-G800 (Rs. 1,000).
I think you meant HS-100 instead of HD-100 for headphones in midrange system.
Btw, despite having different opinion on some components, I have to say you have put up a very nice selection and a big improvement over the previous system (no offense A.Rafay

)
