I am telling you from experience... DO NOT BUY ATA CASES ON EBAY.
Unless it is an Anvil or other reputable company like that. ATA cases are expensive for a reason... and this is one department where you can't escape the "You get what you pay for.." realm.
The ATA cases that use the generic photos like this one:

IS PURE worthless.
The case is poorly made... it doesn't fit right, and worst of all, it warps.
I got one from ebay... it came, it had cracks in the wood, the aluminum valances didn't line up... I couldn't close it without using much force.... I complained to them... and they replied with.. "oh, we do the selling, but someone else actually does the manufacturing... they must've sent you an older version."
They sent me a new one and told me to keep the other one they sent too... the new one wasn't much better... it didn't fit right, but at least there were no cracks.
In about a month, they were both warped... the wood bubbled up like a balloon... so now it really doesn't close right. Needless to say, I've never used the case... I just store spare parts in em.
I went with FlyteCase based out in Canada and got a custom made one for my other amp head. It cost more, but basically... "you get what you pay for".
THIS IS THE Custom made one I got from FLYTE CASE:
