Documenting server details

This could be a very naive question for many of you, but I have problem in answering this one, your help will be deeply appreciated.

I need to document the server on which I work, and it should include following heads:

1. IP address ->
2. Model-> (Dell....)
3. CPU->(@X Quad-core ....)
4. RAM->(48GB...)
5. Adapter external->(Dell Perc...)
6. Disk local->(6 x 1Tb raid....)
7. Adapter external->(Dell Perc ...)
8. Disk attached->(....)
9. Capacity external disk->(.....)

In brackets, I have put the kind of documentation needed for each head.

Is there any one command (shell/bash) or a group of commands that can be used to get this kind of documentation for my server.

Here's a quick script/collection of commands to get you started. Add commands (ifconfig, lspci, etc.) as you see fit:

#!/bin/bash
# hwcollect.sh - Collect general system information

# Hostname
echo -e "$HOSTNAME \n"

# Display system manufacturer, model, serial and other attributes
dmidecode -t 1 | egrep '(Manufacturer|Product|Serial)'
dmidecode -t 3 | egrep '(Height)';
dmidecode  -t processor| egrep '(Socket|Version)'
# Calculate installed RAM
dmidecode -t 17 | awk '( /Size/ && $2 ~ /^[0-9]+$/ ) { x+=$2 } END{ print "\t" "Installed Ram: " x "MB"}'

echo " "
echo "Disk Information"
# Filesystem mounts
df -h
# Display disk partition table    
fdisk -l

I can run a quick ssh loop or run this individually from a source host using something like: ssh targethost < hwcollect.sh

Example:

[root@xetra ~]# ssh Test_Server < hwcollect.sh

Facter, used in Puppet, will collect most of that information for you out of the box. It is fairly easy to add whatever other "facts" you want to collect to it.
