hardware and databases

hello,

If i am planning to developing a web application and host it on my own server.

Application Details

PHP - MySQL running on a linux OS.

what type of hardware do i need. keeping in mind that the number of visitors can be upto 5000 visitors at a certain time of the day.

and will a 2 Mbps DSL connection with a 512 Kbps upload be okay?

thanks

That completely depends on what those 5,000 possible visitors will be doing. Remember that the structure of a database greatly affects speed and performance.
