I ordered this PC to replace my old reliable Optyplex 755 which had coffee spilled on it and died. When this PC arrived it rattled upon removing from its box and had more dust in it than my old never maintenance Optyplex. The rattling sounds was the 3 fan blades that had broken off at some point in this PCs life. From the looks of it I imagine this PC had been left for dead thrown in a corner and powered up and deemed functional and sold to me upon my request. The condition that this PC arrived was extremely unproffesional and will never purchase from this supplier again. I have purchased many refurbished servers and PCs and this has been the worst quality assurance and care I have experienced in my online purchasing lifetime. I proceeded to swap the fan out and cleaned up the unit because the thought of returning the unit and waiting for my money to be returned and shop for another unit horrified me. I am more tech savvy than most and was able to clean and swap the fan and power up within an hour however should never of had to do this. From many of the comments I have read after the purchase I did not even bother contacting the supplier. If you dont want any surprises I recommend you can blindly select any other supplier and will get a better product and service. The condition this PC arrived in speaks volumes...
