Ok, so let's dig into this with a bit more technicality.
You have a FE...and the trade is to give up your FE for an Aorus Waterforce. What exactly do you get out of this deal besides the obvious (obvious being the Aorus Waterforce is technically better than an FE)?
I think we are all assuming your NZXT desktop is not water cooled. If it was, they wouldn't have put in a 3080 FE version. So you have to take it apart, which means taking down the fans, unplugging everything and so forth. You then have to go out and buy materials, accessories and pipes for water cooling. There's kits out there but even with the kits, it's still custom work. You have to measure, you have to think about the pipe route, you have to position your water reservoir/tank/supply carefully, etc.
This is not an easy task. It's a home project. It's like how folks are taking on wood working as a hobby during the pandemic. Measure twice, cut once. Lot of wasted wood, a lot of clean up, etc. You're going to make mistakes and you'll learn from it, but overall it's going to be time consuming.
How much is an hour of your life worth to put this much effort? Actually several hours or even two days. If you're willing to commit to this, then so be it.
But in my personal preference, I don't even want to touch it. I don't have the patience for it.
