"A year ago the total bill of materials (BOM) cost for the Xbox 360 Premium, including hard disk, the DVD drive, enclosures, the Radio Frequency (RF) receiver board, power supply, wireless controller, cables, literature, and packaging, reached $525, well above the retail price of $399, according to iSuppli. Considering the up to date BOM, Microsoft has managed to reduce the pricing of its console by over 38.5%."
So if thats true - Zephur = $325
