I started building the PC, although I don't have all the parts yet (notably the GPU). Honestly, The Tower 200 is pretty fine to build in, especially for an M-ITX case. It feels like the perfect case size in the days where you aren't using large hard drives. Has enough space behind.
My only complaint is that the bracket to hold fans/radiator on the side, well it's wrong. You are supposed to mount AIO's with the tubes at the bottom because of air bubbles, but the holes are lined up so that you can only mount it with the tubes at the top. I did tubes at the bottom anyways, which just means I was only able to put 2 screws in the middle of the radiator to hold it to the bracket. Now while that's likely fine, it's kind of annoying. With tubes at the bottom I wasn't able to fit a fan on the bottom, so that might impact thermals some. I expect it will be okay though.
I went with one of the Be Quiet AIO's, it comes with a bottle of coolant that you can top of the coolant as needed (they recommend 2 years). I didn't know that, that's pretty neat.
