What is your budget? It's entirely about the money.
20000 - 22000 Indian Rupee
convert that to euro or usd and we can help.
EDIT:
Nevermind i did it myself.
It converts to roughly 266 euro. Which is like enough for a CPU and nothing else.
I think you are better off posting the question on an Indian IT forum.
Because we have no idea what the prices would be for PCs or PC parts in India.
