some nice models which may be easily incorporated in 40K without  any harm to the fluff. Models shown are not mine!
Warjacks from warmachine. after applyiing different paint job and some bits they may be chaos robots or thechmarine's robots
armorcast model. not really army choice but i think it would fit perfectly into special scenarios as old sentry bot from abandoned and ancient military base.
Abomination Class dreadnough from Space Crusade. Conversion Beamer is mounted in lower left hard point. model old as the world itself but still very cool looking. if you have any spare, sent me one ;) Eldar Wave Serpent. another model from earlu nineties by Armorcast. in my opinion better than forgeworld's falcon like. and the most imortant aspect. can be seen on 2ed eldar codex and in old epic.
that is a super model. whatta pitty it's not in my collection :(
