Have a look at "Crackers upgrade". (THREAD).
I am building a large but simple system that is MONEY friendly for the size system I am upgrading to. Obviously a smaller system will be even more friendly if done right.
My hint to you is, LFS are the most expensive and friends of the hobby are the opposite, if you know what I mean. You will still need the LFS for some parts, but only when absolutely necessary.
Knowing people helps with cost dramatically.
More than welcome to see my existing set up and im sure they're are a couple of others here that can share info or show you their setups.
Very advisable, as my first set up was LFS orientated and I spent WAY too much.... :-?
Pm me if required and good luck.
