It shouldn't be that hard to hide this quad core. There's an Intel version as well.the imac is not more expensive, its a different machine,
you are comparing an ultra compact all in one computer to a desktop with standard components
if you search for a pc designed like the imac you will find they are actually more expensive (like the gateway one)
it is true that apple doenst make normal desktops, but one step higher the macpro is a damn cheap xeon workstation
so apple is actually very competitive price wise, it just has very limited choise of products
