Your contract is with the retailer (PC World) not the manufacturer (Apple).
Manufacturer warranties are in addition to your statutory rights as a consumer. Your iMac came with a standard 1 year warranty that you chose not to extend... As it has expired, Apple's obligation has ended.
You could try and go after PCWorld under the Sale of Goods Act 1979 (as amended). It's the UK equivalent of the "EU two year warranty" (and has been around for far longer), and like the "EU two year warranty" is against the retailer and not the manufacturer.
The Sale of Goods Act states that goods must be "as described", "of satisfactory quality", and "fit for purpose". "Durability" comes under "satisfactory quality", however how long an item should last for depends on what is reasonably expected for that kind of item.
It you want to make a claim against a retailer under the Sale of Goods Act, you have up to six years (in England, Wales, and N. Ireland) or five years (in Scotland) to do so.
If a fault develops during the first six months it is assumed that the item was faulty at the time of purchase, that is was inherently faulty. The onus is on the retailer to prove otherwise.
If a fault develops after the first six months, it is up to the consumer to prove that it was due to an inherent fault... or that it is a failure of durability as the item should have lasted longer.
