How much would you pay for a dedicated power supply?

[snootch]

All,

Just doing some market research before diving in...
How much would you pay for a dedicated 700W power supply with PCI-e 6+2 connectors to power three 7950/7970 cards?
I've found a good method for modding server PSU's to run three extra cards.
It seems quite a few miners buy extra $150-$200 750W power supplies to run extra cards.
This way, you could run a cheapo PSU to power the board,CPU & RAM, then one of these for three cards. Want to run six cards? Add another one!
The units would be modified server units with 2 feet of wire terminating in PCI-e power connectors, automatically turn on when plugged in, and fan(s) quieted.
I think they would wotk great for any application (Not just GPU miners) that needs solid 12VDC, like shelves of USB hubs or BFL miners.. just add PCI-e to barrel adapters.
I would like some feedback to see what the demand and possible price point of this product would be. Thanks!

EDIT: added specs:

Input:  100-240 VAC /10.1A, 50-60 Hz
Output: +12VDC/57.3A 700W Max.

I'm guessing that 700W PSU prolly cost you <$50 to purchase and configure? That's about what I spec'd out for my 1300W PSU.

Shipping for those are a bitch, tho, cuz they're heavy. You could prolly use a large USPS flat-rate box, which is <$20.

I'd say $85 would be an acceptable price.
