HP Z620 Workstation 2X Intel Xeon E5-2670 2.6GHz 16-Cores Total 96GB RAM No Hard Drive NVIDIA Quadro 600 No OS (Renewed)

False advertising. PC stated that it had a Nvidia video card, part of the reason I purchased this model. You can see from attached picture that the PC had substandard ATI card instead.

Kudos to StallionTek. Product came exactly as described. 16 cores, 32 threads, 96 Gb of RAM for under $600? Insane! A few scuff marks on the case, but the inside was clean and everything works as it should. Moved all my storage from my old PC to this BEAST! I swapped out the rather low-end Quadro 600 video card with one more current and it is awesome. With this much horsepower Im running a good number of the threads on the BOINC platform for the World Community Grid contributing spare cycles to medical research. Seriously though, this thing is a steal at this price and can be purposed to do a lot of things. Great platform to start from. As I run BOINC in a VM, be aware that the virtualizing is likely off by default (it was on this one), and I had to rummage a bit in the BIOS to turn it back on. All-in-all a great piece of hardware and gives a wow experience using it. Im running Linux Mint 19.2 on it and it flies. :)

I already owned a Z620 before and this is one impressive workstation computer so naturally I wanted a second one to replace a failing desktop computer. The one I received Stallion Tek was as clean and as pristine as the first one I had bought from another vendor. The word on the street is they are seeing a second life after being used as servers for Facebook. These are big, powerful machines that cost ten times more when new and the dual processor and multiple-cores combined with the copious ECC memory make them ideal for video (Adobe After Effects is a killer) and 3D rendering such as Poser or Daz3D or as a gaming machine.

Best PC purchase for the money that Ive ever made, and Ive been buying PCs for 25 years now. Im usually running 2-3 virtual machines at any one time on this workstation with zero issue. Subjectively, I experienced a larger increase in workstation power moving to this machine than any other Ive ever bought and paired with the price the value of this machine is unbeatable

Love my new server great product great job seller

I like the capacity of this computer, and I am using 8 of them for my research, large-scale hydrological modeling, without any issue so far. The only downside is that I had to buy cartridges for internal hard drives (SSDs) separately. Great value!!

Its refurbished, what do ya expect? It runs. I slapped an SATA HDD in the included tray and fired up a Windows 10 Pro install off an HP OEM CD. Worked like a charm. This machine operates desktop quiet.

Received the computer a week ago and Im very happy with the purchase. It arrived very well packaged and as described with dual Xeon processors, 96GB RAM, and NVIDIA Quadro 600. (No hard drive) Very clean inside with only a few scuff marks on the outside. Ive had no problems running Ubuntu 18.04 while also running Windows 10 in a virtual machine. Android emulator runs so much better on this computer compared to my old Intel i7 with 16GB RAM.

Exactly as advertised. And works

I have had my ups and downs with two of these machines purchased in January. I set them up with two 1TB Samsung EVO 2.5 inch SATA SSDs in a RAID 1 array. This turned out to be a huge mistake. One of the machines quit working in May. I later learned that the SATA RAID controller on the Z620 motherboard cant handle SSDs in a RAID. The controller destroyed both SSDs at the same time in matter of months.
