Adventum 3 close to pulling the trigger

Budget:
$3,500-5000
Expectations:
High end great looking system. Looking for a water cooled system
Usage:
Gaming

Special Needs:
Something with easy water cooling maintenance, aka accessible drain port and easy filling. I've had experience in the past with cleaning and changing out a flexible tubing loop and hate the idea of dealing with plastic leaching tubing again. How accessible is the loop in the Adventum 3 with hard acrylic tubing?

i would also get windows 10 pro. i think you can ask DS to make u a drain with a ball bearing valve or something like that, but it might cost a little extra. also ask them for  to do motherboard cooling too so instead of only cooling the cpu, the cpu block also cools the motherboard vrams and pci bridge. looks cooler.

personally if i got the aventum 3 with hard tube cooling i would pay  extra to get it painted inside and out. this gonna cost over 1000$. but for me i think its worth it because the aventum 3 case is a real nice case. the custom paint on it will make it look unique. also this case will last you a long time. its not a piece of hardware that will get outdated. you can build pcs in that case for years to come.
