WiLL X TrEmE

Boot CD & type /arch/setup
Source: core-local (only if you have the core iso, else core-remote) note: core-remote works with both versions of the ISO. You'll end up with the latest packages installed.
Pick nano as your editor unless you know vi :P
Clock: UTC (localtime if you have a windoze partition)
Auto Prepare HDD (if you plan to use entire disk)
Select grub as your bootloader (it's pretty robust)
Select base, sudo (netcfg & wireless_tools if you use wireless :D) & install them. (type pacman -S base-devel if later you want the extras)
Configure system
-rc.conf
-check timezone
-change myhost to your desired cpu name (ex: sasoria)
-/etc/modprobe.d/modprobe.conf: add the following lines to disable beep

blacklist snd_pcsp

blacklist pcspkr

-/etc/hosts: be sure to see your hostname
-/etc/locale.gen: uncomment your locale
-/etc/pacman.d/mirrorlist: uncomment for your country & some extra close mirrors (e.g., Canada & US in case a mirror is down :D)
-Set your root passwd & click Done
Install Bootloader (check menu.lst & see if all cool) & select your main HD & Reboot
Login as root & ping www.google.com to check your network (for wifi network here's what to do: # ifcfg wlan0 up,# iwlist wlan0 scan,# iwconfig wlan0 essid "MyEssid" key s:asciikey, # dhcpcd wlan0)
pacman -Syu & reboot if there was a kernel upgrade
useradd -m -G users,audio,video,wheel,storage,optical,power,network,log -s /bin/bash yourusername (add "lp" to the options if you use a printer)
passwd yourusername
pacman -S alsa-firmware alsa-utils alsa-oss

-alsaconf (detect snd card)
-run alsamixer as normal user (su - yourusername) to adjust vol(m to unmute)
-save settings by going back root & run alsactl store
type nano /etc/rc.conf to add dbus & alsa: DAEMONS=(dbus ... @alsa)
pacman -S xorg-server xorg-xinit xorg-utils xorg-server-utils & pacman -S xf86-video-your_video_card (note: to know your video chipset type: lspci | grep VGA)

type nvidia-xconfig (if you have a nvidia card), else

Xorg -configure & # cp /root/xorg.conf.new /etc/X11/xorg.conf
(note: xorg.conf is optional so if you do not use it, grab arandr to change resolution or you can use a proprietary utility such
as nvidia-utils for nvidia cards)

pacman -S openbox obconf obmenu lxappearance consolekit
Once openbox is installed, move menu.xml & rc.xml to ~/.config/openbox/ in your home directory:
# su - yourusername
$ mkdir -p ~/.config/openbox/
$ cp /etc/xdg/openbox/rc.xml ~/.config/openbox
$ cp /etc/xdg/openbox/menu.xml ~/.config/openbox
edit your ~/.xinitrc and add the following:
exec ck-launch-session dbus-launch openbox-session
YOU'RE DONE. Reboot, login with your user & type startx to access your empty desktop and customize your archbox to your tastes

Here's some tips to setup OpenBox
1) obmenu is a your best friend if you want a GUI to edit the menu. Open in a terminal obmenu and create a shortcut to obmenu itself :D. Now that you have a GUI to edit the menu, the rest is pretty straightforward. Create sub-menus and items to the categories you desire and to your applications. For a complete guide on openbox, check urukrama's guide. One of the most complete ones for OpenBox. You could also check the wiki about it :D
2) create an empty file called autostart in ~/.config/openbox in which you'll autostart the applications you need to have a nice desktop. Here's my autostart for example:

#to restore the last wallpaper used in nitrogen
nitrogen --restore &
#your taskbar
tint2 &
#Thunar's file manager
thunar --daemon &
#conky system monitor
conky -q &

3) OpenBox is pretty light and needs extra applications to do the rest of the job. Like you saw in step 2, there's some applications you'll have to autostart to have a comfortable working environment but you could use other alternatives.

Besides nitrogen to handle wallpaper, feh is pretty good!
I personally prefer Thunar over PCManFM
tint2 is nice but another good alternative would be pypanel
Conky system monitor is so versatile and so lightweight since it's text-based but it's optional to use it

4) It's a good idea to create a menu item to obconf to change your OpenBox theme and settings. note: put your saved themes in ~/.themes/5) Another good menu item would be one to open lxappearance to change your window theme & icons. note: put your saved themes in ~/.themes/ and your saved icons packs in ~/.icons/

6) Here's my conky configuration in case you use it:

background yes
use_xft yes
xftfont Sans:size=8
xftalpha 1
update_interval 1.0
total_run_times 0
own_window yes
own_window_transparent yes
own_window_type desktop
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager
double_buffer yes
minimum_size 200 200
maximum_width 200
draw_shades no
draw_outline no
draw_borders no
draw_graph_borders yes
default_color white
default_shade_color blue
default_outline_color white
alignment top_right
gap_x 12
gap_y 12
no_buffers yes
uppercase no
cpu_avg_samples 2
override_utf8_locale no

7) If you use nitrogen as your wallpaper manager, don't forget to add in preferences the directory where your wallpapers are located.

8) What would be OpenBox without keybindings! You can add/edit keybindings in rc.xml file placed in ~/.config/openbox/. You can get obkey from the AUR if you want a GUI for that. Here's a keybind example (my favorite one lol):
