I would pick up a MC270LL/A if you can find one rather than the 2011 version. The reasons are: (1) the 2011 version has 4 USB ports ( like the 2010 model) but only 2 USB buses and the 4 USB ports are shared with internal devices, so there is no way to have a dedicated port for a USB DAC. This is the situation with all the i5 and i7 Apple notebooks as well. On the otherhand the 2010 model has 4 seperate USB buses so it is easy to find an empty (non-shared) port for the USB DAC. (2) The 2011 also run Lion and it seems that most users prefer the sound from Snow Lepoard and there is no way to go backwards on the new products. There is a thread over on the Asylum where there is more info on this. (3) the 2011's run considerable hotter than the previous generation. Who knows but there is a chance there maybe problems in the future like in some of the Apple laptops that were being fried! I saw where some users were putting their new Mac mini on a cooler pad to help prevent this. There is no need to have an i5/i7 processor for a dedicated music server. Another negative for the Lion operating syatem is that there are more background processes running that can not be easily shutdown.
