"One Pop-Down RJ45 Network port" ??? Pop-down? Does that mean it isn't just a normal port you plug in, but is one of those spring loaded ports that pop out? Ya'know, the things horrible notorious for breaking?
I guess it doesn't matter. Googled the chipset, first result: "Realtek r8169 not working in CentOS" - Sounds good to me!
"Three USB 3.0 ports" - I would seriously pay MORE for more USB ports, even if they are 2.0 ports. I hate having to travel with a USB hub just because manufactures don't want to shove out more than 3 ports these days. At least desktops are better in that they generally ship with 10+ now right on the back of the motherboard, before adding the USB headers for front devices.
"802.11n WiFi (ath9k)" - Doesn't say if it is 2.4GHz only or 5GHz compatible, or if it is multi-channel or not.
So, it is a cool concept, I guess, but I think things need to be tweeked a tad to be more universally usable.
