Well, a bit tricky without knowing exactly what you are looking for, and how much you want to spend. Case will dictate what type of CPU cooler will fit. Either due to an air cooler's height or the size of the radiator for liquid cooling.
A big beefy air cooler that is fairly color neutral:

Still considered a contender for the best cooling/noise ratio for air:

Similar offerings from Corsair and Cooler Master if you like the look of them better.
My personal choice for an all in one, allows for custom expansion:

The version I have is much older though. You can also get similar expandable and even pre-filled loops from the likes of EKWB.com and others.
These would all fit in your Meshify case. You could simply swap out the fans if you wanted them all to match.
As for a case, sky's the limit. If you want more options you can always go full tower, though these days I don't see the appeal. Cases in that $100 range are going to have similar options that the Meshify has.
If I were case shopping right now to replace my Phanteks, I might look at be quiet! silent series. Some of them appeal to me. I've also liked Bitfenix in the past, but that was a little different build for me where performance wasn't as big a factor. Fractal, NZXT, Phanteks, CoolerMaster all pretty big names in mass marketed cases. There are certainly crazier options out there, but then you are looking at the hundreds of dollars. Normally, I would say Caselabs for crazy stuff, but I think they just went out of business due to imported metal going up.
