Their desktops come not even cleaned and for return shipping they want you to pay. It is not renewed or refurbished. Its more like they took it off from the commercial or from the business without inspecting/cleaning the machine before selling them. I didn't want to bother looking inside since the power supply fan was already too dusty. The casing even look like it went through some tough times in my own opinion I don't know how it went through QA saying it was renewed besides a re-image to windows 10.I personally recommend Skytech because of this and never once had an issue with them because I have bought more than from Skytech and they are actually renewed and cleaned. Please do a QA check StallionTek.
