This, along with many "refurbished" computers are with old chip sets and cannot be upgraded beyond a certain point. For instance, the 7010 cannot accept a CPU beyond the 3rd generation (i.e. 3770) which means they will not be compatible with Windows 11. With the right hard drive (nvme or sata ssd) and enough memory it can be made to run fast and can probably suit basic computer usage - even some gaming probably - but it cannot be upgraded to be high-end.This one seems to have been upgraded pretty well - bluetooth, ssd, hdmi, etc. The one I got did not have those. Still won't take Windows 11. Not possible.I'm not saying it might not be worth the money. I bought one, added an nvme in a pci adapter and it runs faster than my work computer. With the SSD it'll probably run pretty well. At this point I'm happy with the one I have after adding the nvme, but I also bought another (HP) that I learned too late will not accept beyond a gen 2 CPU. That one I'm thinking to return but not sure yet.
