Top Performance and Reliability

The PC itself doesn't compromise on performance, and can be built pre-installed with up to 64 gigabytes of memory and an Intel 7th Generation CPU. Famous for their excellent performance/value balance, the Core i5 and i7 processors have a quad-core architecture and under heavy loading, will automatically "Turbo Boost" their clock speed. We also offer the Core i3 and Pentium processors for cost-conscious customers. Regarding memory, we supply a minimum of 8GB to ensure that the machine's performance is not bottlenecked, although upgrading to more will ensure that it has plenty to spare and will always offer excellent responsiveness even when running multiple applications simultaneously. We are now also offering our systems with Ubuntu Linux pre-installed.

RAID Options

Quiet PC Serenity Office system has a choice of two motherboards. The reason for this is to give greater options when RAIDING drives. The ASUS H270-Pro is RAID compatible but it only supports RAID for SATA devices, it does not support RAID for two M.2 drives. The ASUS Z270-A motherboard on the other hand does support RAID for SATA devices and M.2 drives. Therefore if you would like to RAID M.2 drives and maybe SATA devices then opt for the Z270 motherboard, if not opt for the cheaper H270 motherboard.

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.

So 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 choose an SSD or M2 drive as a boot drive that contains the operating system and important programs. A conventional HDD would store other data but remember that if you intend to have a totally silent PC, you might want to forgo the HDDs altogether as they will make some noise due to their moving parts.

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.

Customer Reviews

Serenity Office Quietly Humming


Hunting around for a configurable computer, I eventually found Quiet PC. I ordered the Quiet PC Serenity Office with the Gelid Solutions SnowStorm fan replacing the stock CPU cooler. I was very grateful that staff agreed to replace the fan during their build.

The PC was built and delivered promptly in a very well packaged box with recyclable packaging material. The build is extremely clean with all wiring very neatly bundled.

My first impression on running up the PC from the BIOS with no software installed (I use the Linux Debian distribution), was that the PC was no quieter than my existing elderly machine running in an Antec case. I did not worry initially, but set about gathering some remaining peripherals and then installed all the software without having to change any BIOS settings.

Once the software was installed, I found that there was no change in the sound level, and did then start to worry. After consulting with Quiet PC staff confirming that the BIOS was correctly set, I studied the manual for the Nanoxia case. There is an external sliding fan control inside the front cover that I had not noticed before. It was set in the high position, rather than at the lowest setting: this dramatically reduces the sound level. The BIOS records a CPU temperature of 19 degrees at startup, and even after running for hours the temperature hardly rises above 23 degrees.

My emails before and after delivery were promptly answered. Quiet PC do provide a good service and a machine quietly humming under the desk.
