I really like this computer and its performances but:I wonder who designed the case.The case is designed in such a way that it does not seat level on a shelf as the front of the case has a "lip" which must overhang the edge of the shelf for the computer to seat horizontal!What a strange and very inconvenient idea.The computer performances are excellent but it froze once yesterday afternoon and I had to hard reboot it and again this morning it froze for a few seconds.This makes me uncomfortable.I shall update this review as needed.My computer froze again several times.This morning,I requested the vendor to replaced it.Three days later: Three days ago, I updated Firefox to the very latest release, in fact a beta release,since then the computer did not freeze.I love the performances of this computer.Dec 17 2019Since I have updated Mozilla Firefox a few days ago, I had no more freeze nor crash.The computer is now working flawlessly and I give it a five stars rating.I shall return the replacement computer
