I have ordered many parts over the past few years from overclockers and they are always very good. Shipping is prompt and the cost is competitive which cannot be said about some of their competitors.
I have only ever had one problem with a product from overclockers which was my case arrived damaged due to the courier. I contacted OC and they offered to either RMA the product or work out an agreement with them. I chose to work out an agreement with them as I did not want to go through the hassle of having to wait for couriers to collect etc and since the damage wouldn't bother me too much the agreement was the best option.
Overclockers also threw in some free stuff like an activation code for a game and 3d mark 11 when I bought my full system.
Their customer service was very helpful and prompt and I have had no issues with them.
I would recommend them.
