Well, I did a Word/Excel tally of how many people expressed interest in Codeman's original $99 thread. I counted a "couple" and a "few" as 2 and everything else as 1, except where people explicitly said they wanted more (there were a few 3s).
The total units requested was 80. And that value does not include the posts in this thread asking to be included.
I know that pales in comparison to the 4000 you requested, but that may be your initial purchase order volume. Not bad to start.
If you were at all capable of lowering the cost per unit (don't know how--this is just a suggestion), then I think you might see the majority of 1s become 2s--or do volume discounting. For example, buy 10, get one 50% off (I'm trying to be practical here, so that's why the 11th wouldn't exactly be free--then again, a bakers dozen may help move'em!)
In any event, if these are truly V5s in good working order, I don't think you'll have too much trouble selling them--although it's not like they'll all be gone in a month.
Justme's idea of bundling them with options is important to note.
1)Team of with Jack at Badflash, or any other source you can find, and bundle the the IDE cable *AND* the re-flashed BIOS--this is VERY important, as it lowers the barrier to getting newbies in (and the volume of newbie willing to purchase a single unit at $99 with this stuff bundled will exceed the others wanting 1, 2 or 3+ units).
2)The Torx *security* bit (#8) would be great, but to be practical, it would be better to find a source of philips head screws and replace all the damned Torx's than bundle a bit (since it adds cost).
By do all this, the IOs are set. One can basically unscrew the case, plug their HD and go (in addition to any other hacks they want to do).
As for bundling a K6-2+ or K6-3+ most likely wouldn't work in volume because this requires soldering, etc. which would end up costing you, and in the end us (the consumers) too much. If we *really* want to do that, then somebody else on this board should set up a small business to that end.
Mooner's post about a mini-lab is fascinating. This is actually a fabulous idea. I myself might check out doing this for some of my connections. In bulk, this may translate into an order of magnatude more orders--e.g. going from 80 to 800.
Anyway, there's the current state of affairs for this.
