Quiet PC UltraNUC Pro

- Replaced by the Quiet PC UltraNUC Pro 6

This "Pro" version of the UltraNUC is a fully built Ultra-Compact PC based on the 5th Generation Intel NUC. Configured to your specification with memory, SSD and Operating System, just plug in and go!

The Intel® Next Unit of Computing (NUC) is a small PC kit powered by an Intel Core i3 or Core i5 processor. In its 5th Generation form, it provides responsive performance and energy efficiency at the same time. The UltraNUC Pro is a fully-built PC based on the 5th Generation NUC and measures just 4.6" x 4.4" x 1.36".

Improvements over the standard UltraNUC (4th Generation NUC) include four USB 3.0 ports, better 3D graphics, mini-DisplayPort and mini-HDMI monitor outputs, slightly reduced power consumption and built-in WiFi and Bluetooth. Processor performance has also been increased with the 5th Generation, they are now based around Intel's new Bradwell CPUs.


  1. Probably the smallest PC ever made! Configurable to your exact requirements
  2. Thermally-sensitive fan operates only when needed (usually silent)
  3. We build to your specification and deliver within 7 days
  4. Clean Build™ Promise and original OS+drivers supplied on DVDs
  5. Two year warranty with open-case policy
  6. Ultra-compact motherboard offers many features and miniscule power consumption

Even though the NUC is small in size, it is just as versatile as a full-sized computer whilst being convenient enough to be portable. The mini-HDMI and mini-DisplayPort outputs provide full 4K resolution as well as 7.1 digital audio output, (a capable AV Receiver is required).

You can easily travel with the NUC and simply connect it to an LCD TV at the place you're travelling to - a remote office, hotel room or friend's house. A whole host of capabilities are possible when connected to the internet via broadband. The NUC is the epitome of versatility and portability. Alternatively, you can enjoy an uncluttered desk with the NUC mounted somewhere out of the way - even behind your monitor! (A VESA monitor mounting bracket is provided.)

We offer the UltraNUC Pro in two different versions: a cheaper Core i3 version and a high performance Core i5-based unit. Essentially, the only difference between them is processor speed, because the Core i5 has the ability to Turbo Boost its clock to 2.7 GHz whereas the Core i3 is locked at 2.1 GHz.

Clean Build™ Promise

The price of many pre-built PCs these days is often supported by cash kickbacks from software companies who pay hardware manufacturers to pre-install limited or trial versions of their software and then hope that the customer pays to upgrade to the full version. The downside to this approach is that the new PC comes pre-loaded with a lot of "junkware" which bloats the operating system and can cause severe performance degradation.

Here at Quiet PC we believe that customers have every right to expect the best possible performance from a brand new PC, so every system we build comes with our Clean Build™ promise. We install the operating system (if you order one), motherboard drivers, OS updates and (for Windows 7 only) Microsoft Security Essentials / Windows Defender - that's it. You won't be pestered by pop-ups and nag screens and you can get on with using your new PC immediately without having to uninstall lots of junkware first. Your new machine will boot in super-quick time and will stay running quickly for many months and years to come.

Free hardware support and fully inclusive warranty

We offer free hardware technical support for as long as you own the machine. This support covers any hardware query or problem, including advice on maintenance and upgrades. We regret we can't offer software support or training so we would recommend contacting the relevant software vendor in this instance. Support for Ubuntu can be obtained through online forums or on a commercial basis from Canonical Ltd.

Our hardware warranty runs for two years and is offered on a "collect and return" basis, meaning that you don't need to worry about getting the machine back to us - we will instruct our courier to collect it from you on a day of your choosing, then after we have checked and repaired it we will send it back to you by express courier at our expense. In addition, unlike many other PC suppliers, we have an "open-case" policy which means you are free to open the machine and perform your own minor modifications or upgrades without worrying that your warranty might be affected.
