These mini PC's are epic in performance and they're tiny! These PC's fit in the palm of your hand and contain quite a bit of kick with the 6 Core 12 Thread Intel i5 12400 and Iris Pro style graphics. We also added 32GB DDR4 3200Mhz RAM and a 1TB NVMe M.2 SSD making this system amazing for office and business work. Esports gaming is easy for this system to handle and some AAA titles will work at lower settings too. WIFI and Bluetooth built in, 120W power adapter is included. The case is all aluminum and glass so it does get hot under load but within safe operating temps. In gaming the max temp we saw was 80c but with the glass off it averages down to 65c!
