Dream humidor construction in progress- help?!

VERY QUICK QUESTION,

Does anyone know if red oak is an appropriate wood for the exterior? the only reason I ask is because Darrell says it is decently priced and we are giving thought to using it for the exterior... I ask because I don't want any smells or tastes to be transferred through the inlay wood to my sticks, and once again, I know nothing about wood or woodworking....

Thanks everyone for your help, a few quick replies to this question would be great seeing how Darrell and I are going shopping in about 4 hours...

Looking forward to your input,

Rob
