I have not built a PC in a very long time, and with acquiring a z690 classy I thought it time to just overhaul everything. However I am unsure of what cases are good these day. A friend said get a 5000d Hydro X as it was a good water cooling case. However wanted to hear more suggestions before I commit. I currently have a 1600 T2 that may not fit most cases, and I may have to downgrade. Link of my current build, minus the z690 classy and Optimus PC CPU cooler as they aren't on the site. https://pcpartpicker.com/list/DY3btn. Thank you.

Be quiet 802 case currently not satisfied with the airflow. Take the front panel off and it drops 10C on the GPU. I,m going to put the back door on the front and mod it for fans and filter.

I feel like I have replied to this multiple time, but it keeps getting lost. I used to have a caselabs sm8 (the one where the mobo laid flat), but movers destroyed that PC. The O11 looks nice but seems super overused, and for good reason.

I'm glad you spoke up Nozler because 802 was on my list.

I think I may go with the 5000d for now. It's not flashy and is pretty toned down but more mature looking. The 7000d was a bit to big imo.

i am planning on the 1000D for my new build. should be big enough to let my bear paws work inside of it.. only concern is blowing $1,000 on fans for it.. i mean you got to fill up the slots right?

In my current configuration, I have 23 case fans (including the KPE Hybrid fans.
In it's final form it will have 36.  RGB WINS GAMES!

Or hypnotizes you.  I bet there was a share price bump for the company that made your fans.
 
 

Lian Li Dynamic 011, The ultimate case for midtowers for cooling/configuration options, from air/to aio's and even water cooling. Want something with a little bit more room? The Lian Li Dynamic XL.

Most of corsair's stuff is meh, if you are going to have a 30 series and cool it with air, you are really going to want those bottom fans to keep the temps low.

To be fair to the case There's a 420 rad in the front as intake.and no way I could get the 420 in the top so the airflow is warmed and restricted.
Good luck in your search 🔎

Fractal Meshify 2 Compact. This is my first time using a Fractal product, but I really noticed a serious build quality improvement having pretty much exclusively used NZXT cases in the past. Only downside is it's pretty small, but that's what I get for ordering a compact case.

ENTHOO PRO 2 TEMPERED GLASS. It has good cooling and a lot of room incase I ever want to add more stuff to it.

I use HEDT EATX motherboards, and the best case I have ever used is the 760T, which is no longer available. 

780T, and 750D have the same frame So those should be great, but have a lot of removable HDD bays, and fixed 5.25" bays. 
 
If I were to buy a case for myself today, it would probably be the 7000D/X. 
On a budget I would get the 750D however the 5.25 fixed bays might be an issue if you don't have optical drives. 
(de-rivet the optical cage as an option may require reinforcement).
 
I might consider the 1000D, but that is over $500us
 
These are very large cases.
