dgs - You'll note I very specifically said: "I don't blame them for doing things like that". And it's Castle themselves who sell part-exchanged mobos on their site, which is where I quoted the figure from.
I wasn't saying they're wrong to sell machines like that - they most certainly aren't. What I was saying is that it would be INCREDIBLY naive to think that selling the rest of the machine is non-profit-making, or to quote the poster I'm replying about:
"I guess not allowing kit Iyonixes is really just for ease of support, rather than Castle trying to make money on the mice, hard drives, etc".
Think you'd do better to read the posting before hitting reply...
