“Great service, great product, great all-round experience”

“I generally find buying a new PC to be an unpleasant and stressful experience - cowboys system builders are everywhere, quality is gamble at best and post-sales support usually seems to be an afterthought. No, it’s safe to say that traditionally I have not enjoyed the process of buying a PC.

Quiet PC is the sort of company I like to spend my money with. The web site is easy to use, the components are all good, the build quality is rock solid and the service exemplary. After taking delivery of the system I emailed a question to the head of support late one evening and had a helpful reply in my inbox by 09:23 the following morning.

And good lord, the PC is quiet! I purchased it as a replacement gaming PC for my wife, and the difference is extraordinary - I actually opened the case to check that the fans were turning (and yes, they were). Put it like this: while I’m typing this review into a web browser my wife is playing an MMO with graphical settings all set to max, and my PC is making significantly more noise than hers. If you’re tired of your gaming machine screaming when you ask it to do some serious work, take a trip to the Quiet PC web site.

In short, I am delighted both with my purchase and with the level of service that I’ve received from Quiet PC, and I am very pleased to have found a system builder that I can trust. My wife is also very happy, which of course makes me happy too, and I am now in the unusual position of hoping that my own ageing PC breaks soon so that I can justify buying a new one!”
