i dont want to spoil your thread , i can paste a link from this very forum when recently , a person was selling a machine far better than yours for 7.5k (nego) , it was a double processor xeon , if i post it , only your thread would get spoiled .
plus , please take a look around at olx. i m sure u will reconsider your price . Best of luck.
this 7k i have said is even way too much generous as an evaluation , the rest is your choice , its your thing.
