First time actully building a computer by myself but i have seen it done loads of times. I know that the processor is the wrong socket but i canno find one on the same calibre in the price bracket that will work. Also i am looking for a modem could anyone suggest one? Is the wattage of the psu enough too?
Do i need anything else to run the system?
