I want to build a htpc for my 42" lcd lg jazz 80fr within a budget of 25k(or 30k max)
I want a silent and cool system and it should be able to play hd movies(1080p) with complete smoothness and glory. I need a hdmi slot in motherboard and graphic card so that it can be attached to lcd.
The main specs that i need help are processor ,motherboard , graphic card and cabinet.
