The specs of the computer seem awesome and I have done a lot of research before finally taking a leap of faith. I have just purchased the computer on 11/27/2018 and want post an initial review and thoughts and then will post a video and comments when the beast arrives. I am currently working toward a degree in Management Information Systems and Business Analytics; therefore, I could use the power of the HPz820 but also want to be able to watch movies on my downtime. This has been a big decision and would like others to know about speed and quality of service in real time.  For right now I will give 5 stars and then make alterations if needed later, but I will do a full review and video when the product comes.  I just wanted to give an update to the process and say that this company is very responsive and has indulged all of my questions. I am awaiting the product but when it gets here I will upload a video and give a full review of  the machine.  The HPz 820 work station made it to my house today and I was finally able to get it hooked up after running to the store for a DVI HDMI adapter.  I am happy with the workstation and would like to give thanks to the company for doing a great job an answering what ever question I had. I encourage anyone to buy one of these awesome machines.
