The 217 and C8 seem to be his favourites more C8 thank you
I have one too, really pleased with mine.I have a Lian Li Dan A3, which is you want a smaller case 'mATX' then I'd recommend it, it's nicely put together, fairly well designed and big enough without being bigger than it needs to be really.
I did a build for my nephew recently in a C8 and it was a dream to work in, so much room and easy to keep cables tidy. RecommendedThe 217 and C8 seem to be his favourites more C8 thank you

That Flux SE is tempting, holding out for sub £100 though (no, the penny doesnt count in my eyes!)
I knew about the foam, I just have no interest in a glass panel.
Didn't know about the lower speed fans though, is that even vs the non pro? I'll have to find some reviews.
