First off, the 4 stars is for the Power Supply, which should definitely be beefier, as the model I've bought comes with the RTX 2060 GPU.The rest is an adequate, good looking small form factor that lacks no current technology or connectivity, easy to access for upgrades in a convenient layout with a nice design.There is an issue regarding the GPU which I actually asked about right here, on the Q&A section for this product: The Graphics Cards, specially the RTX line do make an almost inaudible electronic buzz when under heavy loads like hovering around a large Revit model. This is best known as "Coil Whine" and it is due to the current passing through when under such loads and/or high settings gaming. It is not considered abnormal or a reason to believe the unit to be defective. Experienced users and gamers usually run stress tests on the GPU which creates the kind of noise I'm explaining here. Nothing to worry about and you can, and should research this issue over a myriad articles.In my experience with hardware, I have to be really careful on selection and it took me a while to find not only an adequate design and connectivity layout, but also the current scarcity of Graphics Cards globally. Having a RTX 2060 available in such unit for $1.4k tax incl. was a no brainer for me after long research.Highly Recommended and I will buy a couple more for the field.
