Top Performance and Reliability

Because we use a fully-featured motherboard, the PC is a very capable unit. It can be built with up to 32 Gigabytes of memory and one of Intel's latest 7th Generation Core processors. Famous for their excellent performance/value balance, these processors have the latest architecture and offer excellent performance. We recommend a minimum memory specification of 8GB for this operating system to perform at its best.

Two motherboards, HDMI 2.0 option

The Sentinel Mini has two motherboards to choose from. The main reason for this is due to the fact we have had many customers ask if it is possible to run a 4K @ 60Hz TV/Monitor via a HDMI port. For this to happen there has to be a HDMI 2.0 port, but it is very rare for a motherboard to have HDMI 2.0 built in. That is until ASRock released their Fatal1ty Z270 Gaming-ITX/ac motherboard which features a HDMI 2.0 port as standard. This means it is now possible to run anything at 4K @ 60Hz without the need for a graphics card. This not only reduces the overall power consumption of the system, as no graphics card is required, but also reduces the cost of the system. Of course HDMI 2.0 may not be required for all customers and therefore we suggest opting for the less expensive ASUS B250I ITX motherboard if that is the case.

Storage considerations

When specifying your new PC's storage options using our system configurator below, you will be offered a choice of drives which vary by price and capacity. There are two primary types of storage. A conventional hard disk drive (HDD) offers huge storage capacity for a low price, but it won't be especially fast and it will generate a certain amount of running noise since it contains a constantly-rotating spindle. A solid state (SSD) or a M2 drive on the other hand, offer tremendous speed and absolutely silent operation, but they cost more than an HDD for any given capacity.

Therefore if you need a lot of storage space (for videos or large quantities of digital photos for example), then we would recommend an HDD. On the other hand, if you prefer silence and speed (especially boot-up speed), then an SSD or M2 drive would be a better choice. Of course you can have more than one drive, so you could have the best of both worlds by choosing one of each! We recommend that customers chose an SSD or M2 drive as a boot drive that contains the operating system and important programs and a conventional HDD to store other data.

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 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 software vendor in this instance.

Our hardware warranty runs for two years and is "collect and return" 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.

Blu-ray playback

If you like to watch Blu-ray films then we offer an optional Blu-ray player which is a slimline slot-loading model. However, Windows does not have the built-in ability to play Blu-ray movie discs and if you would like to be able to do this, we recommend that you purchase third party software to enable the facility. Software such as CyberLink PowerDVD will allow seamless playback and control of Blu-ray movies.

Windows Media Center

Unfortunately Windows 10 does not include Windows Media Center, therefore we recommend you consider an alternative. The most popular are MediaPortal and Kodi (formally known as XBMC). Both programs offer the facility to do exactly (and much more) what Windows Media Center does, although some configuration is required via plugins (add-ons) supplied by both MediaPortal and Kodi. Both pieces of software are open source which means they are free for personal use and they can be used with any Windows operating system. We highly recommend you take a look at them to see if they are more suited to your needs. Please note that we do not provide support for MediaPortal or Kodi.

Customer Reviews

A great little machine


After working solely on a laptop for several years, I got fed up with that and decided to get a desktop for my web development work. But I still required something that would be easy enough to move every few weeks, so I decided on this Sentinel Skylake Mini, Ubuntu pre-installed, i5 6600T CPU with 16GB memory.

It's a good small size; I haven't seen the processor go above 40 degrees; it's very fast with many programs running, at least for what I do (note that I'm not a gamer so I couldn't comment on its abilities in that direction); and it's very quiet. It's not completely silent but then I didn't expect that.
