Storing cues..

Ok, so i have read several post on this and have gotten a jist of what people think is ideal. However, i am wanting to build an inwall display case, probably 15 cues and shafts. I know from reading that upright is not the best way to store cues, however they dont display very well on their side

So..how bad is it really to store cues upright...not leaning, just straight up and down?

Is there a major problem storing/displaying the cues ina basement? My basement is dry, but stays on the cold side..cool in summer colder in winter. It is heated so when i say cold i dont mean that really cold.

Thanks for any advice.

I already have it made

It is already finished, just wondering what the overall effects of storing cues upright, and being in a dry yet cold basement might be.
