My budget is tight at the moment but if I was getting one of these (and I wish I was!), I'd just get a clear-coat and not get ano'd.  They look so cool with the raw aluminum finish.  You can see all of the little marks and get a feel for the CNC work that went into these cases.  Cool stuff.  
Matt - we've never seen CNC workmanship and creativity like your stuff around here.  Looking forward to your future creations.  
Cheers,
