UK: Is this 24k gold-plated iMac the most expensive in the world?

Laban Roomes, the founder of international gold-plating business Goldgenie, claimed to have created the world's most expensive iMac during an interview in London, Tuesday. The specially customised iMac is coated in 24 carat gold and costs £10,000 (€12,506 /$14,244) but Roomes assures it is good value for money.
"Is this the most expensive iMac on the market? Yes it definitely is. But what you've got to remember is - it's not expensive to people who are doing well, who are wealthy and we actually think it's actually still good value for money. So even though it is the most expensive iMac on the market I think for what it is, it's also the best value iMac on the market as well," he stated, before adding: "The type of client buying this would be from, you know, the Middle East, Russia. We've sold a couple in to Russia so far and these are wealthy business people that have everything."
Discussing the production process, Roomes said: "To customise something like the iMac to this sort of level that we do it at, where we're offering a lifetime guarantee, you know is not something which is done overnight. It takes - I would say on average - at least 28 days."
