I have one 7U x 104HP performance case angled on a keyboard stand, not sitting on a desk, and so not using the retractable legs. My question is if I can join another 7U case to it using the Intellijel joiners, even though the legs of the joiners won’t be resting on anything. Will the connection between the two cases alone be stable enough to support the top case?
It’s hard to say without knowing what kind of keyboard stand you are using. I find it’s quite stable having the two cases joined together, so probably if you find it stable enough using the built in feet it wouldn’t make a difference with the joiners.
