Then the problem with THAT is that people would say it's over-priced junk that you can build yourself for cheaper. Alienware and such as an example. And people like us on this forum are the ones that call it over-priced junk that you can build yourself cheaper hehe.
Forget PCs, start raising Llamas or something
Now that we turned this thread into at least a 40% angle from what it started at.
Actually I think going the used PC route is the best way for a low-volume guy to work on. Then you can work on getting the people you sell to upgrades, even used upgrades. You can pick up cheap dual-cores now also. So you get a P4 system for 20-30 in bulk, build it out, sell for $80, then a bit down the line you contact your mailing list of customers and ask "so I got this dual-core PC in, do you want to upgrade your system with a partial trade-in?". I have sold at least 4 upgrades this way, and working on getting two newer laptops currently into the hands of some of my contacts. Plus if you offer good service and value, and explain things well, you have tons of references which can lead to more sales as they tell friends and relatives about this greath cheap PC they got from you.
