Top Performance and Reliability

The PC itself doesn't compromise on performance, and can be built pre-installed with up to 16 gigabytes of memory. Although Microsoft Windows will run happily on 2GB of memory, we recommend a minimum of 4GB to ensure that the machine has plenty to spare and will always offer excellent responsiveness whilst running PVR software such as Media Center which comes with Windows 7 and Windows 8.

Despite its diminutive size, it packs a real punch - Intel's Ivy Bridge processors give fantastic performance and low power consumption, allowing the machine to be cooled without any forced air whatsoever. The whole case acts as a processor heatsink, with heat being efficiently transferred from the CPU to the chassis via two copper heatpipes.

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 - 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.

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 from Sony. Although Windows includes Media Center, it does not have the built-in ability to play Blu-ray discs. To address this issue, we offer Blu-ray playback software from Arcsoft which tightly integrates with Windows Media Center to allow seamless playback and control of Blu-ray movies.

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 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.

Windows Media Center

All three versions of Windows 7 include Windows Media Center which is a great way to watch and record terrestrial and/or satellite TV (in conjunction with a TV tuner card), as well as watching films, viewing photos and listening to music. Windows 8 does not include Media Center but it can be easily added to Windows 8 Pro for a nominal charge by requesting a product key on the Microsoft website. Adding Media Center to Windows 8 also gives you the ability to play DVD films. We recommend Windows 8 rather than Windows 7 because it has more features, faster performance and will be better future-proofed.

Customer Reviews

This PC doesn't support Wake-On-Lan


I've knocked a few stars off this as a warning to others that the Gigabyte Z77N-WiFi motherboard used in this media PC as well as other small form factor PCs in the Quiet PC range does NOT support Wake-On-Lan and therefore there's no way of waking it up from sleep mode or shutdown remotely, either with a remote control or via a network connection. You have to go over to the PC wherever it is and fire it up manually. It's hard to believe we're in 2013 and there are media PCs on the market without WOL but there we are. Very disappointing.

Quiet PC replied on 9th May 2013

You are indeed right the motherboard does not support Wake on LAN, which is also disappointing from our point of view. Although it is possible to turn the PC on/off or even put it to sleep/resume using a USB remote control.
