To be fair, the cost of dual-proc Xeon motherboards at retail probably reflects their low sales volume. I'd imagine that every motherboard manufacturer (Abit, AOpen, ASUS, ASRock, and then the Bs) feels compelled to offer one in order to complete their product range, but they probably sell 100 or 1000 times as many £30 motherboards for Celerons. I don't see anything on a dual-proc motherboard that would make them inherently more expensive to build than a single-proc one. Older Xeons used to require an additional voltage regulator board, but I don't know if this is still case. Nevertheless, most of the expense of these boards is R&D, so Apple must be able to absorb that somewhat, if they're only manufacturing Xeon-based m/boards for their towers. Additionally, it seems to me that Apple may well have the largest sales-volume of Xeon-based machines, spreading the cost. > That Mac's are more expensive on anything other than the low end is > fast becoming untrue. I believe this has been the case for some time. Nevertheless, I believe that the hackintosh article doesn't simply raise the question of what someone might expect to pay for a comparable PC, but what they might expect to pay for a PC which meets their needs. Were I buying a machine to run XP or Linux on my desktop I certainly wouldn't be looking at quad- or eight-core Xeons - it is only Apple's limited range that pushes me in that direction, and I would be quite grateful for a £1000 Mac tower.
