    You might want to consider using your ISP's web space rather than local
    space, for the following reasons:

    1. Upload speed (the speed at which your machine will serve pages to the
       internet) is generally slower on ADSL. The ISP's machines will be
       well-connected.

    2. Security - you don't need to worry about accepting incoming httpd
       connections if you use the ISP's space.

    The ISP appears to believe that you need a sledgehammer to crack a nut.
    You might need a PIII-450 if you're running Windows, and you want to do
    all your web browsing and stuff on that machine.

    I have a 512k ADSL line, and my firewall/router is IPCop, running on a
    486DX2/66 with 32 MB RAM and a 1 GB HDD. It's a bit pushed (I'm not
    running Squid or Snort), but it's coping OK.

    Depending on what you're using it for, it's probably fine. If you want
    it to work as a desktop, running KDE, OpenOffice, etc. along with handling
    the ADSL line, then you might find it a bit slow. Otherwise, it's massively
    over-powered for just routing, firewalling and webserving. If this is what
    it ends up doing, you might like to reduce the clock and/or bus speed to
    save power and prolong the life of the hardware - otherwise, it'll spend
    most of its life twiddling its thumbs...

    Of course, it depends on your ADSL hardware. If you buy a cheap USB ADSL
    modem, then it might require lots of CPU horsepower to replace the functions
    that the modem should be doing (like a winmodem). You'll also be at risk
    of getting a modem which has no Linux drivers. However, if you buy a
    nice external router, the CPU load should be minimal.

    HTH...
