I agree Antec are superb. Alongside Hiper have given me the joined best after sales service.
My situation was I was having problems with the fan on my Antec Solo case, it was making a periodic grinding noise (and no nothing was touching it).
Contacted Antec on the understanding that I would likely need to post to them my faulty fan for them to swap it. But instead they just sent me out a brand new Tricool fan.
I will compare this after sales service to Coolermasters after sales service. Had a faulty 850w Real power PSU which I had bought from a competitors store than OCUK.
It was out of the 1year warranty by a few months so obviously well in the 5 year warranty Coolermaster claim to offer.
RMA request ignored, 2nd RMA request also completely ignored.
Email to Coolermaster technical support address, ignored, emails to every coolermaster email address I could find - ignored.
Waited a month and tried another RMA request, ignored, sent further emails to all the Coolermaster email address all ignored.
Was left in the situation of I was not sure what to do, as I paid £110 for that PSU that was faulty. What is the point of offering a 5 year warranty if they don't even want to honour it.
In the end I contacted that competitor store and explained the situation and told them that I did not want another Coolermaster product as they don't honour the warranty, so even though it was out of the 1 year warranty they swapped it for a Corsair HX620.
It is a serious shame that Hiper went out of business, who were fantastic, and Coolermaster have remained.
