Details from the official site:
The Nintendo Wii SUPREME Officially the most unique and expensive in the world. Six months of precise workmanship went into creating the ultimate gaming station which boasts over 2,500 grams of solid 22ct gold. The front buttons are home to 78 x 0.25 ct Flawless diamonds which total 19.5 ct. Available as a limited edition of only 3 to be made.
Price is at £299,995.00, conversion to US currency $483,883.
This is Kotaku's take on it:
Recession? What recession? Liverpool England's Stuart Hughes likes to cover electronics in gold, call them SUPREME (his caps, not mine), and ask INSANE (my caps, not his) prices for them.
His latest project is the Nintendo Wii SUPREME, for which he wants the equivalent of US$483,883. The console contains 2,500 grams (88 oz.) of solid 22ct gold and the front buttons house two 78 x 0.25 ct flawless diamonds. The total of both diamonds is 19.5 karats.
The total value of the gold and the two diamonds is considerably less than what Stuart Hughes is asking. What's more, you'll have to play your SUPREME Wii with a NORMAL Wii Remote.
Let's say that the gold is US$1,000 an ounce for a total of about $88,185. And the diamonds are about, say, $400 a karat for a total of $31,200 for the diamonds. Both bring the grand total to almost $200,000 — not including the price of a Nintendo Wii. Stuart Hughes site says that it takes six months to make one of these things. Stuart Hughes' time is very valuable. Six months will cost you, give or take, $283,000.
