Here is the story, my web server that I pay for has become unreliable. I have an old computer in my room hooked up to the cable internet (LAN) and the specs are as folllows:

Win 98
2x 2gb hds
64mb of ram
cd drive
floppy
low end pentium II

I need to run a web server, mysql, and php. I am pretty sure i could manage setting this up with a linux distro, but i'm not sure which is the best and i am definitely not sure about security. thats why i put this in the web security because i want to make sure that this box is secure but can also be viewed by ppl outside the LAN...

questions:

best distro for job
security procedures
overall install procedures

thanks guys
