Krunker took an old mac mini, upgraded the ram, adding some external hard drives, an external HD TV tuner, installed vista, and ended up with a very usuable vista media center pc.
Here’s the summary:
“In this article, Iâ€™ve gone over the high level elements that Iâ€™ve undertaken to transform a Apple Mac mini into a Windows Vista Media Center system. At the end of the day, the Mac mini makes a solid and capable Media Center box. Itâ€™s even better when you use the system in conjunction with Media Center Extender systems since the Extenders can deal with the actual video processing and rendering. There are of course some limitations with the Mac mini – mostly in the areas of storage and expandability. Storage expansion can be solved via external hard drives or via a network attached storage device such as Windows Home Server (and Iâ€™ll delve into that in the near future). Additional capabilities can be added to the Mac mini via USB connections although it does destroy the simplistic look of the overall system a bit.”
