Here you go but this one isn't under your budget, it's coming nearly around Rs. 67K but you're getting a full build with everything like Optical Drive, LAN and WAN cards etc. etc. so, I think it's worth it because your budget my friend is extremely low for a gaming PC and below this it won't be a gaming PC so, here's the link: http://pcpartpicker.com/p/RszKQ7
PS: I forgot speakers, extremely sorry.
Note: You have to get the parts from Amazon.com or if they are available in India it's good but in both the cases they will go above your budget so, sorry.
