Thank you, Dragonlich. Your comments have been useful.

I have built all my computers using MyCom for over 20 years :-)
Starting with a 386sx. I miss the printed catalog!
It's much harder using their on-line catalog. It's buggy too.
Yes, I'll have to talk to a salesman. It will be worthwhile.
I have time. I just put in a used power supply in this machine and it will be ok for a long time. Since it was open I increased the memory to 2gb. The panic is over :-)
I'll make a list of my thoughts and go to MyCom.
They also have a phone service. Perhaps I should try that.

Yes I would like to continue to use the HP720 (I also have a spare 710). I would be surprised if Win7 has a good driver for it. Win XP does not. Graphics only 72 dpi.
I never could get 300 dpi with XP.
I don't know what printer to get. I almost never use a printer. What printer uses economical inks?
IDE ATA was to use drives I have but a new one TB drive and the fact that DVD writers are so inexpensive (and come with new systems) means I don't need it. Thanks for pointing that out. I would like to have a serial port. I wrote a phone dialer program in Delphi 8 years ago and still want to use it with a modem. I'm strange.
