I ordered 2 of these to replace my Windows 11 incompatible systems.  The product description indicates they have an optical drive and a 512GB PCIe SSD.  One of the systems had an 800GB SATA SSD and the other a 480GB SATA SSD.  Neither of the systems had an optical drive.  I was going to send them back but then I realized  they were still a good value.  They did have the PCIe slot available and I was going to clone my old systems to upgrade.  I really don't need an DVD drive and have a portable USB3 if I do, so I bought 2 PCIe 512GB SSDs and replaced the SATA SSDs they sent.  They should send what they say they are sending.I probably should have sent them back but they are working well on Windows 11 with very little extra effort on my part.  I'm just out the SSDs and optical drives.
