Ok so I am pretty underwhelmed by the specs/price ratio of the new mini. I am thinking of getting the cheapest base model, and upgrade it myself to make it beefier. - 4gb RAM. ( Any chance at all that more RAM would be possible?) - 320 GB 7200 rpm HD. ( Does a larger HD with 7200 rpm exist?) - Quad core CPU. Ideas for what HD I should get? - Would it be possible to use a Quad core CPU? A) Will any quad core cpu fit in the socket? If so which ones? B) Will it work with the OS? Anyone else thinking of doing the same?
