I have the system76. Not bulky at all. Mine has no CD slot but an SSD and 500 GB internal drive. Been playing steam games just fine on the Iris pro graphics, it controls 2 external monitors simultaneously (3 in total including laptop screen), drivers for everything worked out of the box (although Skype for linux is acting up wrt audio). Add to that: System76 support is great.
Edit: I should add that keyboard and clickpad seem to annoy some people but I haven't found anything unusual with them as laptop input devices go (they all give you RSI anyhow). I only use them on the go when I really need to but use ergonomic ones via USB most of the time.
