This Lenovo mini pc is in excellent condition. The model of this mini pc is 91B20000UT and it has 16gb of DDR5 memory running at 5600 mhz (can be upgraded to 32gb). It features the Intel Core 7 Series 2 240H with 10 cores and 16 threads and 24mb of L3 cache. It has a 512gb ssd that is PCIe 4.0 and has an additional ssd slot that can hold a 2TB ssd but I found no reason to upgrade as the connection for an external drive was very quick because this Lenovo has a Thunderbolt 4 connection.It has 1 USB A 2.0, 3 USB A 3.2 and 2 USB C 3.2 ports with one of those USB C ports being a Thunderbolt connection with the option for display port out. In total you can run 3 monitors simultaneously with a Display Port out, HDMI 2.1 and the USB C thunderbolt.Last pic shows that I completely cleaned the fan before preparing for sale (even though it's still relatively new). I reassembled it, tested it using geekbench and then factory reset it. It is cleaned and ready to go!This mini pc runs perfectly. Questions....don't hesitate to send me a msg.
