The Lian Li cases are nice but I really want a side window. The Elysium is kind of cool but I don't like the top.. I will consider the 650d but I like the size of the 800d!
Also, I plan on upgrading to water in the future and would like the option of a 360 rad and I like that I can throw a 360 in the top of the 800d or even mod it for a 480. It's just so expensive...
I'm all about Aesthetics and Function, and it has both. Those other cases recommended are cheesy in form and/or function. Not even worth the $$$.
As the old saying goes... You get what you pay for.
