[CentOS] 'Many' packages installed - CentOS 4.1

Hi

Installed my first CentOS box last night after coming from Whitebox - 
This is perhaps me being stupid but on install i opted for 'Custom' 
install as i prefer minimal and then build as i suit. I went through the 
list of things to install and removed everything apart from networking. 
Install happenned and tons of stull ended up being installed including X 
openoffice and the like - Why was that when i de-selected everything 
apart from networking? It was very much bloatware and not what i want on 
a server.

thanks for any hints
