quick answers needed on the imac specs

No.

 

In the current iMacs, the optical drive is a mobile one. I think the GPU is the mobile version as well.

 

RAM is mobile, in the sense that most laptops use the same kind of RAM. It's 204-pin DDR3-1333MHz PC3-106xx.

CPU isn't (I think). It's standard voltage, not low voltage or ultra-low voltage like in laptops/ultrabooks

HDD is 3.5in. So no, unless you have an SSD, which I'm guessing is 2.5in.

The GPU is a mobile version, I think.

Power cord is... not mobile? I mean, it's sort of your standard power supply cable. I guess laptops use them (some at least). It's mobile in the sense you can unplug it and frolic with it, yeah.

 

GPU is AMD Radeon HD 6750M, 6770M, or 6970M. The "M" is for mobile.

Also, my understanding is that there is one 3.5" HDD bay and one 2.5" HDD bay in the current iMacs, hence why you can get both an HDD (3.5") and a SSD (2.5") in a single iMac BTO.

They used mobile CPUs (CD, C2D) in earlier iMac, but since 2009, Apple has switched to desktop CPUs, just look the specs up at www.everymac.com and then visit ark.intel.com using the CPU model EveryMac gives you, to see, that the i5 and i7 in the current iMacs are in fact NOT mobile CPUs as you may have misunderstood.
