High spec gaming rig to swap

Description:

Looking to swap my gaming rig for a Macbook, must be in excellent condition and preferably the 15.6 inch size. Specs of my rig are as follows....

AMD FX 4100 quadcore 3.6ghz

Gigabyte GA-78LMT-S2P (Socket M2) Motherboard

8GB Dual channel ram

1TB HD + 500GB HD

HD 7770 Graphics card 1GB DDR5 ( very good card )

PowerX Viper modular PSU 650w ( Bronze 80 plus )

2 x DVD RW

Zalman Z11 High performance plus case ( 2 led blue fans, 1 normal fan and side door exhaust fans )

Running Win 8.1 enterprise and office 2013

Very very fast PC and CPU stays under 12 degrees even under load. It boots very quickly also.

Currently have COD Advanced warfare, Shadow of Mordor and Watchdogs installed which run flawlessly on the GPU.

I can also include an Acer 27 inch LED HD monitor ( HDMI, VGA and DVI inputs )

Many thanks
