I'll try to keep this brief, since there's no need to read my long personal saga with this crap. The computer came with the cheapest (wired) keyboard I have ever seen and the cheapest (wired) mouse I have ever seen -- more like thin plastic toys than computer equipment. So if you want a real keyboard and mouse -- especially wireless -- you have to buy them separately. The ridiculous HP DisplayPorts require you to buy special adapters to hook standard HDMI monitors to it. So, again, another extra purchase. But -- most hilariously -- the PC had no wireless adapter! So if you want to connect to your home Internet wirelessly -- that is, if you live in the year 2021 -- that's another purchase you need to make.  I emailed their customer support (which their brochure promised would respond in 3 hours), and I never got a response. And that was now a week ago. I didn't waste any time with it. I packed it all back up and sent the trash right back where it come from and got my full refund. I wouldn't make this mistake again.
