I'm sorry if I insulted any general public out there, I have removed the word stupid
@joel: $500 would actually be reasonable. You gotta realize, your labor of assembling this thing counts for something. Lot of name brand computers start at $600 or even more just to have a low end dedicated graphics card in them. Not everyone can build a computer. Now can't be any more than $500 I don't think, mainly because this desktop won't have a warranty like a name brand assembly.
I think anybody from 10+ who is not disabled can learn to build a computer in a week
Proving exactly why your labor is partially a factor. Some people either don't want to bother learning, don't have time or patience to learn, don't want to take the time assembling it, or worse, find getting the hang of actually using a computer a headache enough.
