Apple's overpriced hardware has proven really suspect lately, thats because they are using ECS and Foxcomm Motherboards and parts.
Apple uses Foxconn motherboards, or motherboards manufactured by Foxconn at least. So does Intel. So does almost everyone.
Foxconn is the largest manufacturer of electronics and computer components worldwide, and mainly manufactures on contract to other companies. Among other things, Foxconn produces the Mac mini, the iPod and the iPhone for Apple Inc.; Intel-branded motherboards for Intel Corp.; various orders for American computer manufacturers Dell and Hewlett-Packard; motherboards for UK computer manufacturer Zoostorm; the PlayStation 2 and PlayStation 3 for Sony; the Wii for Nintendo; the Xbox 360 for Microsoft, cell phones for Motorola, the Amazon Kindle, and Cisco equipment. - From Wikipedia.
