<< Why would anyone purchase a Dell???
The $799 deal uses the Intel 810 chipset, very hard to upgrade, and
if something goes wrong, all you can do is use the "recovery" CD
which wipes out your hardrive.......
I'd go with an outfit like NuTrend......build it with the parts you
want and you get a regular OS CD............

Read the original question, the user will probably never upgrade. If someone needs to ask another person just to buy the computer, then the buyer obviously doesn't have the capability to build his/her own. Older users most often need to write a one page letter, check email, browse the internet, etc. All of these uses do not require saving important data to the harddrive (The user would probably see no problem with the harddrive wiped out).
I personally would check only major manufacturers with free and quick customer service. The user would get more benefit from this than from saving $50 on a home built machine. I like Dell customer service (10 minutes average wait), Gateway is not as good (30 minute average wait).
