OK so we're going for mITX, just one final debate, do I save money and go with a Corsair CX 430 and risk having cables snaking around everywhere or do I spend more an go with an OCZ ModXStream Pro 500W and have some choice over which cables I use?
it's 10 euros, if that matters much to you then get the cx, you can tie them up somewhere up top and really you shouldn't need to open it up much for what it is.
