If you're just interested in keycaps only, go for G81-****H**/H**** as NO ONE will cry about throwing away MY boards. For G80, it depends a lot on the model. While 11900 for example are not bad keyboards they are not really too sought after either. But if it's perfectly good no reason to trash it. Some models on the other hand like the 2000 are quite rare, and many would want to kick you in the balls for taking just the caps off of that one. Then you have some really old G80 models with model numbers under 0600 that may be XT only. Some are very rare, some not as much. Since they generally aren't usable without modding it might be debatable on parting it out, but it just depends on the model. Same goes for many newer models made between 2006-2009 where the only thing interesting about it is the doubleshots and it is otherwise identical to current production.
