The minimum requirements for memory and drive spcae are based on space not speed or performance. The minimum requirements is what is needed to run the software, not what is needed but more will make it run better. The challance is null and void, because even if I wanted to entertain the notion, there are not sticks that small that will run in my system. I would be suprised if I could find a 256 MB or even a 512 MB.
If you are putting together you system to impress other, you are a bigger looser then I thought you were. Put it together for yourself, and what you need, not to be popular with people that only understand buzz words.
