I have the HAF922 and had to make a simular choice when deciding which case to get. It is quite difficult with all three having special qualities that made them unique!
Firstly, I liked the Lancool but reviews hinted that it may not have enough cooling potential and may be noisy. However I still liked the tool-less design and the look of the case.
I really liked the antec 902. It has the best cooling potential as stock and has dust filters and black interior. The only thing that put me off is the way the hard drives were positioned so that it would look cramped if you had many of them and may affect even more if you had a particularly long video card (Gtx 470 should be fine)
The HAF 922 was the largest case out of the three, a lot of room to work with and a lot of space behind the motherboard tray to tie down cables. It has difficult to remove dust filters at the front and drive bays but regular dusting is recommended anyway to reduce a build up. The inside isn't black but a slightly shiny bare steel. All in all a larger deeper case for simular price as other mid towers out there.
