For Lian-Li to cut the cost to under 99, it must sacrifice a lot of features due to the more expensive aluminum cases.
The one you are choosing does not come with Lian Li 's latest tool-less design as we see in the Lancool Dragon Lord series...no black interior and less cooling features.
It does has the benefit of its higher end aluminum cases - light weight and strong, quality Lian-Li production.
The one you should really compared 690II to is Lancool K62.
Both cases are feature packed budget cases...both come in trendy black interior...both have excellent cooling.
K62 has better tool less design, better intake filter
690II comes with more freedom on fan placement...with area for watercooling radiator, to me it has better look.
So I went with 690II.
