I second the recommendation of ArchBang. It's a very lightweight LiveCD (~500MB) with a GUI installer that works pretty well. If you're comfortable on the cmdline, you could search the official archlinux forums, though. There are quite a few arch setup scripts floating around. You could try this one for btfs on luks: https://github.com/atweiden/pacstrapit

    ./pacstrapit start --bundle    "full"                \
                       --username  "newusername"         \
                       --hostname  "yourhostname"        \
                       --partition "/dev/sda"            \
                       --processor "intel"               \
                       --graphics  "nvidia"              \
                       --disk      "ssd"                 \
                       --luksname  "infinity"            \
                       --locale    "en_US"               \
                       --keymap    "us"                  \
                       --timezone  "America/Los_Angeles" \
                       --concealed
