Beauty and power in your living room
We are pleased to announce this ground-breaking example of living room PC - the revamped Quiet PC Sentinel Fanless i18. A perfect compromise of beauty and practicality, it is just 250mm wide and 110mm high so small enough to fit virtually anywhere. The machine is supplied in a shot-blasted silver, black or titanium finish and its fascia is clean, elegant and uncluttered. Only the power button, power light and remote control sensor (optional) and two USB 3.0 ports are visible on the front of the case.
Top Performance and Reliability
Because we use a fully-featured motherboard, the PC is a highly capable unit, designed to handle a wide range of demanding applications. It can be configured with up to 64GB of high-speed DDR5 memory, ensuring smooth multitasking and efficient data processing. Additionally, it supports Intel’s 15th-generation processors, which are well-regarded for their impressive balance of performance and value. Built on Intel’s latest architecture, these processors deliver excellent computational power, improved efficiency, and enhanced support for modern technologies, making the system both powerful and future-proof.

Intel Arrow Lake 15th Gen 35W Processors
Intel’s 15th-generation 35W processors offer the primary advantage of low power consumption, which in turn reduces heat generation. This enables the use of smaller form factors and facilitates quieter operation, making them ideal for fanless systems. They also offer lower running costs compared to higher-wattage processors. While a 35W processor may not deliver the same raw processing power as its higher-wattage counterparts, it strikes an excellent balance between efficiency, reliability, and performance, making it a strong choice for a wide range of applications.
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 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, but remember that if you intend to have a totally silent PC you might want to forgo the HDDs all together as they will make some noise due to their moving parts.
Clean Build™ Promise
These days, many pre-built PCs often rely on cash incentives from software companies to support their prices. These companies pay hardware manufacturers to pre-install limited or trial versions of their software, hoping that customers will eventually opt to upgrade to the full version. Unfortunately, this approach has a downside: it fills the new PC with unnecessary “junkware,” leading to an inflated operating system and performance issues.
At Quiet PC, we firmly believe that customers deserve the utmost performance from their brand new PCs. That’s why we proudly offer our Clean Build™ promise with every system we build. When you choose one of our PCs, we install only the essentials: the operating system (if requested), motherboard drivers, OS updates and Windows Security. Say goodbye to annoying pop-ups and nag screens. With our clean build promise you can immediately start using your new PC without the hassle of uninstalling numerous unwanted programs. Experience lightning-fast boot times and enjoy optimal performance for 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 at least 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.
