Hello there

Dual quad core boxes are fairly popular in the workstation ./ server arena

What gets me is the motherboard manufacturers don't make a dual Q6600 or Q6700 based motherboard. All the dual processor boards seem to be Xeon based which means they are rather pricey.

Only the server chipsets offer the multi socket solutions. The motherboard manufacturees use desktop chipsets for these CPUs because they are much cheaper.

As an example, I am thinking about upgrading my Apple Mac Pro from 4 cores (2 x Intel Xeon X5150's) to 8 cores (2 x Intel X5355's).
Server CPU : Intel X5355 is 4 cores @ 2.66 GHz. Cost= $776
Desktop CPU : Intel Q6700 is 4 cores @ 2.66 GHz. Cost= $279

Yep, gouge the server users because they're willing and able (and with the different sockets are forced) to pay far more than consumers

I agree that the server

I agree that the server hardware have steep prices, however they do have to be a lot more reliable than a PC. I guess that's one explanation for the higher price.

(I should mention that i have no experience with server hardware, so I cant say if it truly is more reliable :)

Server hardware is more ruggedly-built than regular desktop hardware. It has to be, since it's going to be running 24x7 for a lot of years.

Besides being more rugged

Besides being more rugged there are a lot of features built in that you'd never find on either a desktop or a work station. Memory mirroring, RAID memory, hot swap memory, hot swap PCI-X or -E cards, L4 cache built onto the cpu boards, main memory on each cpu board, slots for more than one memory card, choice of 2 or 4-way interleave on main memory, ChipKill on the cpu boards, N+1 hot swap power supplies, hot swap fans, connectors for adding external PCI enclosures, 2-12 (or more)hot swap drive bays built in, ......

Heck! When I win the Lotto I'll buy one just so I can sit and watch it purr .... :-)

Don't forget the painfully loud fans. Packing enough cooling air flow into a tight shape means absolute horror. Forget 120mm, 90mm, or even 80 mm fans rotating at the modest speeds required for decent acoustic noise. Say hello to tiny fans turning horribly fast, with the sound to match.

Oh, yes, conservative server design dictates that the supplied fans should be enough for reliable operation even after a failure (maybe more than one failure), so the required rotation speed or number of fans is even worse than you thought.

I'd not share my living space with one voluntarily, at work or at home.

With the rest of my Lotto money I'd get high quality hot-swap earmuffs, and of course build a dedicated walk-in fridge for the viewing times ... :-)
