Agreed. But, even if he just charged for the parts, but no labor, then the purchaser will still assume some kind of support would be provided.
Heck, I see computer shops in my area, charge just $40 to $60 to assemble a computer. If I were to do such a thing, I'd be so screwed. Charging such a little amount, means that the first support call you get, you'll go into the hole on the deal financially. Then again, I'm not sure of such warranty that they're providing.
I'd say: 15 days labor / 1 year parts. But, spell it out. If anything is going to die (e.g. memory, etc.) it will do so very early on. By spelling it out (e.g. - labor will be provided after 15 days for a charge of $45 per hour, with $30 for the first 30 minutes being charged as a minimum labor fee.) However, keep in mind, that usually these details should be provided up-front so the purchaser will know what they are getting. Other wise, they just assume that you'll give them a 3-year warranty or so.
Best of luck ... I have a feeling you're going to need it.
