I understand your point with the warrenty and fast repairs but I could have like 5 speres of every part just laying around for the price thay are charging . But I also don't think it needs this mutch ram and we acces everything over a network that is limited to 3MB/s, that does not mean however that trip can't be needing faster data transfer than that. But we also had it running on mutch older hardware and I don't think it needs that fast of IO.
I will call Dell directly and ask, thanks for the advice. And if I can let a professional IT guy do it I would rather do that dan be responsible myself. Of course also "proffesional IT guy companies" have competitors and I heard that they are cheaper and as good. My plan is to just get to what we need and see witch one offers the best deal also considering warrenty and replacements.
