Although it looks weak as you take a quick look at its specifications, the 1037U Celeron this slim-PC uses is enough to adequately deal with office applications. Its embedded Intel HD 2500 VGA surely won't allow you to play the latest 3D games, but that is not this system's main prerogative as it mostly addresses business environments or users that need a small and completely silent slim-PC for applications that don't require a ton of computing power. This system's many I/O ports and the ports installed to its front panel greatly enhance its usability; its USB 3.0 support is the cherry on top. The DS437T also supports the fast SATA III protocol, so you can install a fast SSD to fully exploit its SATA III capabilities. Install an SSD and it will boot into a generally snappy OS in no time. I installed Windows 7 x64 on my test sample and really enjoyed working on it. I am pretty sure a free Linux distribution will run even smoother on this PC's hardware, and without hurting your wallet as much. The 1037U dual-core Celeron CPU obviously is strong enough for a user without terribly high demands, and it is also incredibly power efficient, which would allow you to run your system around the clock (24/7). Shuttle's official certification even states that this product can handle operating around the clock despite its passive design.
To wrap up, if you need a slim-PC of high build quality and zero noise output, the DS437T is a perfect candidate. However, you should keep in mind that it isn't meant for applications with high computational demands, or 3D gaming.
