Update1/6/21: One of the RAM modules went dead today, necessitating a lengthy troubleshooting session. It wouldn't boot, no video, just 3 short and one long beep. After some internet research,I got some ideas to try and eventually, through numerous attempts to boot using different combinations of memory mods, I was able to identify the bad one. Still a nice machine, but could be a little tricky for less tech-minded buyers.Original review:My computer arrived in near new condition and cleanliness - if you look very closely, you can see a minor scuff. Everything works perfectly except one of the USB 2.0 jacks on the back, the other 7 (4 USB 3.0) work fine. I can't hear it running at all. It's being used as an always-on living room HTPC and couch surfing machine. I'll add a video card for moderate gaming, but it is a fast machine! It replaced a 2.16GhZ Celeron notebook and the speed difference is very noticeable - even browsing is friskier. Streaming is hiccup-free and downloads faster even on my cheap 4G connection.I've just had it for a month, but it has been a real pleasure thus far. I used to build my machines, but I couldn't put together something this capable for this price. The keyboard and mouse are AST branded and seem inexpensive, but they work fine and I use a nice Bluetooth set 90% of the time, anyways. As others have noted, the Windows 10 Pro 64-bit install was clean, activated, and free of junk software.
