A:AnswerComes with vertical stand however I am currently using it horizontally in my entertainment center as a media PC. It has feet for horizontal use and only components on “bottom” side are the ssd & memory, CPU has air intake from front/top side exhausting out the rear.
A:AnswerMy model came with a 128gb SSD stock for drive size/type. Also included was a 2.5” drive cage and cabling. I was able to add another SSD/HDD using the drive cage. This answer will vary based on drive setup from Lenovo as they sell this with just HDD which uses the 2.5” drive cage but should have open m.2 slot then.
