i have decided to sell more components (RAM + PSU) and also changed prices...but i cant edit the post like on gamer.lk after some time.
if u want any further info PM me ill post the link (admin says i cant post gamer.lk links on topics)
btw...the stuff im selling comes to around 104,000 so that leaves you with a monitor and the small accessories like mouse n KB to buy...to fit your budget of 120,000 ( increase it buy 10K more and i can suggest you a really good system for some gaming goodness)
