Ram????

Hello folks,
I want to buy a Xserve G5
Im wondering how much RAM will i need to run the following tasks 24/7 and all at the same time. I dont need the best performance, but very decent performance.

- Apache
- Mailman
- MySQL
- php
- FTP Access
- Remote Desktop Connection
- 24/7 Internet Connection

I know the more the better
But im trying to save some cash
Thanx

Hmm... Not really sure, but I am going to give a around about guess

Apache.. 512mb
Mailman.. 512mb
MySQL.. 512
php.. 512
FTP Access... less then 512, but go 512 any way
Remote Desktop Connection.. depending on how demanding 512mb-1gb
24/7... not that much.. very little
extra 512, for good luck

so I guess 4352mb ram 4 and 1/4 gigs.... I am not sure.

I have seen servers run on less than 512. But I would say get a minimum of a gig.
