Is a full tower neccesary for effective water cooling?

[ChTender]

I'm working on my first water cooled build. Is a full tower necessary?

I'd love to push the form factor smaller.

Planning to run an i9-9900k, 2080Ti, 1TB Sumsung Evo, EVGA Platinum 1600 PSU (already owned)

Thinking about this case https://www.coolermaster.com/catalog/cases/mid-tower/mastercase-h500p-mesh-white/

Would my PSU even fit?

(Sorry for the bump, I'm unable to find an "edit" function)

There are a few examples out there of people water cooling cpu and graphics cards in mini itx cases so water cooling is definitely possible in that case you have selected as it can fit two 360mm radiators in. It will still be tight in places but very doable.

As for the psu I can’t say if it will fit. I couldn’t see any information on the website. The 1600w though is way over kill and if you didn’t already own it no one would recommend for you to buy one that powerful.

It's definitely possible, but I would suggest a WC focused case, especially for your first build. I hope you're planning on a minimum of 6x120mm in rads. Dual or single loop? I find videos like this to be helpful.

You might look at the Corsair Obsidian 500D. There is a build by Jayztwocents on youtube with it https://www.corsair.com/us/en/obsidian-500d-case
