This "renewed" PC looks brand new with no scratches, dings, or dust.  I removed the cover and the inside is also dust free and perfect.  There is room for 2x 2.5" Drives or a single 3.5" drive AND a 9.5mm slim optical drive.  The SATA cables are already installed on the mother board and waiting to be connected. All of the parts are Dell original and as described on the Amazon page.  Last, I did not need any tools to open the case or to install components such as a disk drive or optical drive. Great design!Windows 10 was installed (and activated ) and it when through the usual Windows setup questions.  I did have to run Windows Update a few times but no problem.  There is also a Dell program installed that updated some drivers and the BIOS.  Very easy and painless.When powered up, this PC is absolutely quiet and very fast - it boots in under 10 seconds.  The only thing I needed to add is a USB WiFi dongle.  All-in-all, I'm VERY PLEASED with this PC!!!
