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

works excellent speed, unfortunately it arrived very mistreated parts of the cabinet broken fortunately the board and components without signs I did not want to return it since the equipment was urgent, more care in the packaging

I have no problem behind the curve if it comes with 96G of RAM and 32 cores.

This thing is built like a tank. Added a 500Gb SSD, a 4Tb HDD & a free download of Windows 10 Pro. It rocks now.

It came just as advertised!!!

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. :)

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.

I got this machine because my other computer was dying. It took me a bit to get it running because of using custom OS, but even with that tech support was great. I had to contact support several times and after doing research, working with them and snooping around the computer, all the problems were correct.

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.

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.

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!!
