The memory type listed in the Item name is DDR4, which isn't true for my rig. It was actually DDR3, and I had to return two memory modules and buy two additional RAM sticks with the proper memory type for upgrade purposes.There's a bit of work ahead of you if you plan on replacing the graphics card. I had to edit the power allotment to the PCIe 16 slots via the BIOS to get my preferred GTX card (1660 Super) to properly communicate with the motherboard, and if you are a casual owner, that may turn you off from trying to upgrade the thing. Additionally, I know that an upgrade to WIndows 11 (ugh) will be necessary, so I'll have to find a workaround to the system's incompatibility with W11 which could, again, turn off casual users.That said, once I got things to work, this workstation is absolutely great! Runs my creative software very well, and has the bonus of being a decent gaming rig, able to play pretty current titles at 1080p at respectable frame rates (some in-software adjustments will be necessary).Good project machine for those comfortable with building PCs using repurposed hardware. Dropped a star off bc the listing is a little misleading as far as specs go.EDIT: Something to note for casual buyers getting this. This computer in particular is VERY finicky about the memory you need to upgrade. It's basically a requirement to get 2133 mHz memory sticks, and at least four for a quad channel setup. Look at the labels on your memory sticks. If it has "PC4-2133" anywhere on the labels, you're good to go, otherwise you might be out of luck. ALSO, your memory should also be ECC-registered.
