I knew this was a refurbished machine, but I’ve had great luck with systems like this in the past. Not so this time. I don’t even know why they bother including the mouse and keyboard they sent with this thing. Yeah those went into the trash. Just put a piece of candy in the package with the tower And monitor. Make more people happy.I bought this machine a couple months ago and the USB ports are already failing. The machine itself doesn’t have a WiFi adapter card, it’s a usb WiFi adapter and so since the USB ports are failing (or something is) the WiFi is unstable. Since I use the machine for work, that makes this set up blow. All of the usb gear I plug into my laptop and it all works just fine.I have contacted the seller and I did buy the extended warranty. I’ll see what they say but so far the experience has been “meh”.
