Pros: Configuring the device is simple. Form factor is attractive for a SOHO environment. HDMI output to act as a local PC or Media Center is a novel feature.

Cons: *Software updates remove important supported features* Lack of documentation. NFS Performance is very poor (2 MB/s for v3)

Overall Review: I purchased this device on January 1st, 2016. One of the standout features was the virtualization station, which allows the user to create virtual machines and switches. My expectations of the virtualized machine were low, because it's a virtual machine running on a NAS. The virtual machine performed perfectly, albeit slowly, but beyond my expectations and certainly above my need. A software update in April removed the virtualization station feature. As a cautious user I check the update notes before any upgrade, it did not list removing virtualization. When I discovered the issue, I immediately called the support number during normal business hours. I stayed in queue for 45 minutes with no answer, before leaving a message. Three days later I have not received a call. While waiting, I submitted an online trouble ticket with no response. There are further complications to the update. Since the update effects the file system, downgrading to a previous version may corrupt the stored files. Making downgrading a potentially catastrophic operation, where all files and the virtual machines are unusable. As of July 9th, 2016, QNAP still lists this device as supporting virtualization at https://www.qnap.com/event/station/en/virtualization.php?content=supported . Yet, the feature is still disabled in the 4.2.x firmware. More importantly, the feature was listed as supported when the device was purchased. Silently disabling it through a software update without any notice is not only a poor process, but smells of a bait and switch. In summary, QNAP silently removed a feature through an update with no safe method for returning to a previous firmware version. The feature that was removed was included in the supported list at the time the device was purchased, and after the update was in place. Using the advertised customer support methods is pointless, since they will not respond to phone calls or trouble tickets. Do not buy this device if you care about features remaining present, and do not buy a QNAP device if support is important to you.

Pros: Partially worked for 2 years.

Cons: The USB device problems were never resolved after months interacting with ASRock support. Their final solution was for me to pull the board, send it to them, and await repair. In the interim I would be without a motherboard. While that may seem reasonable, it leaves me without a computer to work from. This support practice would necessitate buying another motherboard while I waited for the repair of the ASRock board to be completed. Which is of no help at all. I spend more money to get a product I already purchased repaired. After two years, the board died. It fails to power on or post. I have no interest in pursuing an RMA or support issue with ASRock based on my previous interactions.

Overall Review: The entire experience with ASRock support has left me frustrated and annoyed. No longer will I purchase their products. MSI and Gigabyte will get my business, and possibly ASUS (since ASRock is a spinoff).
