: Imagine hot swappable web server hard disk. Plug your disk straight into : the switch, telnet in, configure apache, upload content, done.
Right.
: I believe it's possible, but I think Larry's estimates of 50% extra cost : ($200 -> $300) are off the wall. The Itsy shows you can make Linux boxes : small enough, but the pricetag (several thousand $) also shows that it's : economically impractical.
Err, I was an architect at Cobalt, before that SGI, before that Sun. I've designed and shipped products from all of those companies, both hardware and software products. I'm intimately familiar with the Cobalt Cube BOM, having gone over it and over it looking to reduce the cost by a nickel here and a nickel there. I've done the same thing at SGI and Sun (though at Sun I was on the other end of some of these discussions, the most wacko of which was the serial port argument at Sun).
Whatever, I'm sure my experience is very boring, but that same experience says that it is very doable to put an embedded processor down on the drive and ship it at at a profit for an extra $100. It won't have much memory, probably 8MB, at that price, but can definitely be done. Don't underestimate the power of volume. And customers will deal with having to buy extra memory.
The really nice thing about 3.5" drives is that people aren't concerned about power or heat at that size (laptop drives are another matter). There are a bunch of people making processors which are designed to deal with heat/power but they are all for laptops (and carry the related laptop markup). We aren't talking about that market, we can afford all the power we want and heat isn't an issue in this config. There are lots of processors that would work for very little money.

That's extremely misleading for this topic. You are confusing the "limited to stock on hand, customer limited to 1" throw-away-at-a-loss price with production prices. I'll personally kiss your ass in public in front of rolling cameras if you can show me a supplier, today, right now, who will deliver 10,000 units of 100Mhz pentium, 16MB, motherboard, case, 100baseT, guarentee a DOA rate of less than 2%, and guarentee a run rate of an additional 10,000 a quarter.
Can't be done, dude, I know, I've tried. And I put together machines all the time, I know exactly what it costs to get something that works. You do pretty much get what you pay for.
So, sure, I'm willing to believe you can buy one machine like what you described but that is very, very different from a production run.
Oh, yeah, don't forget the cost of assembling that stuff. When I was at Cobalt, it was looking like about $25/box just to put it together.
