Quiet PC Serenity UMX PC

Built around the excellent Jonsbo UMX3, the Serenity UMX PC is quite possibly the most attractive small PC that accommodates high-end components we have provided.

Building a PC around the Cooltek-Jonsbo UMX3 chassis was a must as soon as we saw it, it is such a great looking case it had to be done. The full brushed aluminium outer casing and minimalistic design give it a sophisticated high-end feel. It measures just 365 x 188 x 358mm making it extremely compact. One would think that due to these small dimensions there would have to be some compromise regarding the components it can accommodate - that is not the case. A top of the range Kaby Lake or Skylake i7 CPU and the Nvidia GTX1080 can all be installed with this chassis if required, meaning you can achieve high-end performance in a small but elegant PC.

The best quiet / performance balance

Any air-cooled PC will always be a compromise between quietness (arising from careful cooling design) and performance (which produces heat). This situation affects gamers even more than most because of course, the latest and greatest processors and 3D graphics cards tend to be the ones which run the hottest and which have the loudest fans on them.

We’ve done a lot of development work in this area to bring you the Serenity UMX PC - a fully built high performance PC which we think offers the best of both worlds - virtually silent running (especially under light loads), and extraordinary performance with great cooling design which gives total safety and reliability for your precious components.

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 64 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.

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.
