Question Difference corsair hydro h50 CW-906006-WW variant and non CW-906006-WW variant

Hey everyone, short question.

Looking for a simple AIO for my storage build, and I found the corsair H50 for like €25,- on my local online marketplace. However, I read that there's a difference between the H50 itself; it can either be the CW-906006-WW variant or not.

TL;DR: what is the difference between both H50's? Is it like a new revision or do the two models have different dimensions?

What I can see from my little research is that the H50 either comes with a big, bulky cooling block or a small flat one. Might be the difference between 'em, but I'm not sure
