Does anyone know of any sites that have case building info.

I guess it would depend on how much of the case you would want to build completely yourself. I would think that the use of for instance drive bays from an old case would be a lot easier than building everything yourself.
Even if you want to build every component yourself I would look at other cases and take the best ideas from each and combine them.

Also having been in metal work for some time I hope that you have access to sheet metal tools and knowledge in the trade. Then again the most important ingredient is self motivation.

Good luck

Ya...tuck and roll black leather with some shiny black studs.

Yea, with two inches of insulation. You know, to keep the components from getting cold.
