Still fresh, damnit!
That might be something ED could check in a future video; wiping the painted case with 70% alchohol soltutions and checking whether the paint comes off.
The heat sinks should not block the cases being painted, so I suspect ED will send the cases to the company as soon as he gets them, providing the company is open. And I'd be very surprised (to answer the actual question you asked now I read it again) if they haven't been ordered before the first post was made. Practically the only way you find the lead time of an item is when you search for it on farnell or aliexpress or wherever you're actually buying your bits and pieces from, and then you're only a couple of clicks from actually ordering it, so I suspect he pushed the button and started the process.
