I've had this for just a few days but it's already up and performing very well for my needs. The combination of the 8 core processor, 64gb RAM and SSD hard drive looked to be perfect for my scripting and number crunching needs, and it's proven to be as hoped.  I did notice that there was no mention of wifi capabilities so reach out to the seller to verify if you need that or go ahead and plan on getting a PCIe wifi card as I did. With any "refurb" situation there's always a possibility that things aren't as perfect as new but I feel like I got a great value for the cost and would do it again.
