Pros: This is a great little PC for it's size. It's fast, quite and the added VESA Mount is a big plus. Easy hardware install and has room to grow if needed.
Cons: The only Con I found has been the Wifi adaptor. Realtek usually is pretty good but this one is just pathetic. I had the unit sitting 6in from AP and could watch the signal just go up and down. I tested it in WIndows 7, 8.1 and Ubuntu 13.04 and all gave the same results no matter what driver I used.
Pros: Very quiet with just little fan noise. In response to some of the other comments about fan noise. I suppressed to find out it had a fan, also. When I first heard I thought the unit was frying. Even playing a game the noise is extremely less than my mid tower case. I am thinking of get an i5 unit for a friend.
Pros: Lightning fast boot times with the msata ssd. Light enough that it doesn't affect the vertical orientation of my monitor when mounted on it using the VESA bracket.
Cons: While I was setting it up on a desktop, I accidentally browsed my fingers across the power button several times, unintentionally putting it to sleep. This wasn't an issue once I got it mounted on the monitor but I can't help but wish the power button had a bit more tactile resistance before registering contact.
Pros: It runs well, and loads in 15 sec. after I upgraded the SSD.
Cons: After I got Window8.1 installed and drivers in. I took it into anther room and started it on Wi-Fi. I could only about half a signal and it was dropping like crazy. Come to find out Wi-Fi card only maxes at 78 Mbps and that is next the router. So I'm upgrading that, so we will see what happens. The Blue Tooth isn't much better, it only connects to items right next to it.
