I am extremely close to buying one of these, but I just noticed one fatal flaw, at least for me.
Have a look at this photo provided by Lian Li:

In particular, note the bundled up usb cable for the keyboard. For a $1000+ desk/case, I simply would not be pleased with that. Even worse, at this point I'd only be using the mini-ITX side (on the left), so my mouse would have to plug in on the left USB bank, and its cable would have to run across the length of the keyboard tray to my right hand.
While a wireless keyboard and mouse fixes this, I'm a heavy gamer and much, much prefer the wired versions.
I was looking at the assembly of the keyboard tray, and there doesn't seem to be any space at all to run a cable through. Ideally, all Lian Li would have to do is create 3 clean holes at the seam of the keyboard tray (left, center, right) - where it meets the desk, and this problem goes away. (I would run the cables cleanly underneath the desk.)
Yes, I realize that when pulling out the system drawer you'd have to ensure enough cable slack, or disconnect the mouse & keyboard, but I don't think I'd be opening things up too much after assembly.
Anyway, just about bought this today, but this held me back. If anyone has any ideas/workarounds, I'm all ears.
