Yes, we know about the z97's in india as I even mentioned it above
The reference to the z97 extreme4 was that the z87 version is probably just as good as it.
We gave you 3 good options and you have 2 from your original post; the Asus z87-A, Asrock z87 extreme4, MSI Gaming, Asrock z87 Pro4, Asrock Killer
The Extreme4 is out of stock and if you don't want a z97 then it's out to. So you have the Asus and the 2 original Asrocks. They all have 3 year warranty. The pro4 is the cheapest by 3000rs, so you are probably better off going with it. If you only want to overclock to 4.5, then most 1150 can achieve this.
I would say get the pro4 and Seasonic 620w and be happy with your new build
