If you want more opinions, it would be more effective to bump your old threads. Multiple threads on the same subject make them seem like dead threads and will put off forum users from participating. Your budget is tight but i will put something together now. Considering the budget, fufilling all your requirements and leaving you a rig that could play arma 2 at playable settings is tight and making the parts good enough to last a while would be impossible.
Here is a build minus the OS. You can use a 3 month trial OS untill you can afford a new upgrade, this way you can afford a rig that will be able to play the games which will come out next year.

The build is also overclockable with a CPU cooler. Overclocking on one of these CPUs is easy and can be learnt by watching a few videos and reading a few forum posts. It will add a year or two, performance wise, to the lifespan of your rig.
Stretching the budget by £30 will net you the 8320 instead of the 6300, which is worth the extra 30 for sure. Another route you can go to save money is going for a trinity set up with onboard graphics. This will easily do minecraft but it will struggle with arma 2, whenever there is some action. The above spec will easily out perform any trinity APU set up. There are however, new APUs coming out at the end of this year or early next year, which might be worth waiting for. Here is a trinity spec anyway:

It is worth noting that:
-the A8k can be replaced with a better A10k, if you can afford it.
-Without the extra graphics card to xfire in this build, you will have a considerable performance drop in many games.
THIS is an example of game play with this build on arma 2.
You are best going for the 6300 build out of both of these, it will last much longer and you can upgrade the CPU and GPU if you need to. Both these builds require a half decent overclock to get your moneys worth though. It is worth trying.
