I originally purchased one of these towers on 11/24. I figured I could save a few bucks and the planet in one go, so I was happy to purchase a refurbished option. I plugged it in the day it was delivered (12/8) and turned it on to test it, but it didn't seem to be operating correctly. There was no damage to the box and no visible damage to the tower, so I assumed it was because I hadn't connected any monitors to it yet. I tried again on 12/12 with monitors and that's when I discovered the tower wasn't working at all. The fan would run for a couple seconds, then there would be a loud beep, then nothing. I will say the IT line was somewhat helpful in troubleshooting. We tried a few things then they decided the tower was in fact defective and emailed a return label the next day. A replacement tower was delivered on 12/28. I thought it was working great, until a couple days ago when I realized all 3 audio ports are not working. It's Jan 10th now, so it's not worth me going through the whole process again for an audio port issue, but I'm beyond frustrated and wish I had just bought a new tower to begin with.Additionally, they send a wifi adapter, mouse, and keyboard with each tower, with no way to opt out of receiving those. The adapter I tested with the working tower was a complete joke. It wouldn't hold a good connection, so I tossed it in the trash. I didn't need a keyboard and mouse to begin with, and when I returned the first tower, they said NOT to include the accessories the tower came with. So now I have 2 keyboards, 2 mouses, and 2 wifi adapters that I've trashed. Plus, the eco impact of shipping and returning products that should not have been defective to begin with.... This is not the eco-friendly choice they claim it to be.
