I do not have a video card for it, but will buy and install at buyers expense.

I can also add or customize this to whatever the buyer would want.

I am a service manager for an industrial computer company, so I have built thousands of computers.

I will do a full burn-in and test of the unit before shipping, and also help with warranties if something goes wrong.

What would be an appropriate price for a brand new system?
$750? obo sound good?

500?

500 sounds about right to me.
I wouldn't buy a vid card to sell with it, unless requested to do so by the purchaser. most computer buyers looking for a basic system would only go online with it.
