For my first ITX build I wanted something with a small footprint that could accommodate a triple fan GPU, so the SSUPD Meshlicious was an easy choice. I chose the EK AIO Basic 240 because of the sub-$100 MSRP and EK's reputation for high-performance liquid cooling, and it does well. The 9600KF and GTX 1660 Ti pairing is great for 1080p gaming and their temperatures are low and easy to control.
