Nehru Place is Asia’s biggest IT hub with an estimated daily turnover of Rs. 10 crore which is continually growing? I found this out in the website’s FAQ’s section. Another useful link is the buyer’s guide (pretty outdated) in case you’re a little confused about what to buy.
There’s a lot and lot of room for improvement for the website but none the less, its still useful. You can check prices of hardware and software and get details of various vendors here and decide what to buy before you actually go there to make a purchase.
