But cooling needs to be taken care of, I have an Intel P4510 attached to it and an Intel P3700 card directly on top. While these are two different generations, they differ by 10 degrees (and U2 is warmer). Pay attention to the temperature when you first build your computer, get some real-time monitoring software (I only use nvme-cli intel temp-stats tool on Linux), you can relax after finding out that everything is safe. NVME and airflow take time to settle into the desktop chassis.
