Mac Mini mods?

ok so i searched high and low, macrumors and google and i cant find what im looking for. Just curious what type of mods have been done to the mac minis. Im not talking about a simple RAM swap but things like case mods, 3.5 hd swaps, etc.

I found good info about the 3.5 HD swap but just curious do i need an external HD case? or can i buy some sort of power adapter where i can just connect to the HD itself without a case so it can just hang loose in the open next to the mac mini.

*edit* i found the power adapter here but just curious about any cool case mods or over clocking mods or anything for the first gen 1.42 mini.

 

no no no
