This review is for a system bought from ITreplay.  Shipping was in an air bubble wrap that protects it very well in the box. There were no details on the type of SSD as the Optiplex 7600 SFF takes NVME and SATA M.2 SSD and SATA SSDs. They didn't reply to the question on the product page.  What I got was a 512GB Micron M.2 SATA SSD rated for 550MBps read/500MBps write.  I was going to replace that anyways with an NVME drive.  Looks like the original Dell RAM (SKhynix).  Relatively clean inside and out. There was a missed dusty section on the power supply intake on the inside that a broad vacuum cleaner would miss.  I had to use a finer vacuum.  It came with a Win10pro for refurbed sticker but the PC was digitally licensed for Win10pro anyways when I did a clean install via Windows Media Creation Tool created USB drive.  It came with a generic keyboard and standard Dell mouse and power cord.Original Hard-drive caddy was there along with 2 of the SATA cables. Be aware the power supply only provide one SATA power and one CD drive power. If you plan on installing 2 SATA drives via a dual 2.5" adapter you'll need a SATA power splitter.
