first water cooling setup-new case or mod current case

[Zairs]

Looking at doing my first custom loop, done lots of reading and am more confused that when I started! Lol
I want to water cool both the cpu and gpu, and then I started looking at radiators and what I should fit and now I'm confused and not sure what would be the best thing to do, I have a large custom case that has lots of empty space. Now I could alter the case again which could be a good idea. I do have access to metal workshop so making new a back on the case and altering the internal positions of everything is easy enough)
Or I could just buy a new case
I want to go for a silent setup so was thinking of a couple of rads or a large one.
Also could a mount a radiator and fan back to back on another radiator fan set?

Honestly I would get a new case. That one looks fairly beat up and it looks like it would be more effort than it would be worth to mod in rad space. Plus the max you could fit would be a pair of 240mm rads which aren't going to be the quietest.

Go for a new case, one with decent radiator support.

The Phanteks Evolv looks good.

+1 for a new case unless you were thinking of a battle damaged theme!
