Linux distro on Dell PowerEdge R300

[Bogdan Stoica]

Hello people. I just bought a Dell PowerEdge R300 and I want to install 
a linux server on it. I was thinking at installing Slackware 12.2
I will have Apache, proftpd, bind9, mysql, and postfix and a file server 
probably. Wich is the most recomended distro for this, and what is the 
best partition setup? 4 GB RAM and 2x750 GB SATA hard drives. Thank you.
