Overview
- The finalized mini-ITX system pairs a Ryzen 7 9800X3D with an Nvidia GeForce RTX 5080 and a 600W Flex ATX power supply.
- Billet Labs reports the radiator weighs about 178 pounds empty and roughly 218 pounds when filled with coolant.
- A custom water loop moves heat through copper plumbing into the radiator body, with the RTX 5080 peaking near 75°C in testing.
- To mount hardware on the curved base, the team 3D-scanned the radiator and installed a two-part 3D-printed chassis with slim 120mm fans.
- The builder describes the PC as suitable for long-term use but says cooling a higher-power GPU like an RTX 5090 is likely impractical.
