This bundle is one of the best I have ever seen for the value for money.
I don't like bundles myself because i'm a do it yourself type of person but for someone who isn't confident in building their own PC or overclocking and on a budget, this is definietly the bundle you should buy. All you need to do is add a PSU, case, HDD and GPU, something like the CM 690 II ADV a 6850, Samsung F3 1TB and a 500/600W PSU and for around £600 including the bundle you have yourself a decent little gaming rig.
