I wanted a fast and slick system, integrated in my room but out of the way, comprising two computers. It took some planning and time but I'm very pleased with the result. System 1 is a Threadripper with 2080 videocard, system 2 is a i5 8600K system. One of the partitions of the Ikea cabinet has been heavily modified to fit both systems. Radiator at the bottom blowing warm air up through the system. Power supply at the top will, if the fan is not idling, suck the air up and out.
