It it's for April or May, there's no point in recommending anything now, the prices of the components vary a lot, what might be a good deal today, it might not be for tomorrow, also some parts by then might be discontinued or other new stuff coming.
Worth mention, there's the release of the new intel haswell cpus in June(official).
So my suggestion is, if you can hold another month for it, and then open a thread here by then.
Will do. Thanks a bunch.
