Pros: For refurbished, came extremely clean of dust (looks almost new - some minor cosmetic stretches on the case) Fast CPU, RAM. A client of mine and myself each bought one. Using it with Windows 10 Pro, IIS/.NET and Windows 2016 SQL Server for local intranet .NET application and file server. We both put in a 512GB SSD for the OS drive and 2 internal 6TB spinners. The fans are quiet on both units. Includes fans for the RAM. Also on mine, I have PLEX Server running for media streaming in addition to file server, IIS/.NET applications tied to MS SQL 2016.

Cons: No cons really, the included internal drive on one of the machines is going out (grinding) about 5 weeks later; so replaced that. We didn't put any OS or other programs on it (was only using it for a mirror image of the 512GB SSD. But not docking for eggs on it as who knows how that drive was used before being refurbished.

Overall Review: We also had custom made "DEMCiflex " dust filters (one) for each PC to put on the front of the workstation. Amazing as to how much dust that captures before going into the case.
