There are quirks but these machines come with a remarkable price-to-performance ratio.  Power button can by finicky bc of case fit, SSDs are the lowest quality to expect to upgrade if you want performance.The best kept secret is after spending the time to download and read the manual, there is an M.2 NVMe connector on the main board!  It is under the existing SSD drive and easy to miss.  Upgrading to NVMe  makes the drive feel as fast as RAM.For those interested I can confirm Ubuntu 22.04 runs great on these with power mode support.  If you throttle it down to the lowest setting it is nearly silent.
