This is my first custom water cooled build. I wanted to use all Phanteks parts that I possibly could. I used some parts out of my 2 year old Alienware PC Area 51 Desktop R2. I mainly just used some drives and my fairly new graphics cards. All lightly used and very new. However the graphics cards are GTX as I am not yet convinced about RTX and the new tech ray tracing. Plus my GTX cards are very new and lightly used. I simply converted them into liquid cooled blocks.
