Lenovo's latest consumer-grade IdeaCentre is a PC of no more than one liter (L) in capacity, yet packs specs also found in larger up-to-date desktops, Thunderbolt 4 and HDMI 2.1 included. It has also come to CES 2023 with 13th-gen Intel processors. With its partially-recycled chassis and upgradeable RAM/SSD storage, it also checks sustainability boxes.
