Well, I met the Stacker in person today at SVC. I was highly impressed but ultimately walked away from it for a few reasons.
1) Only 1 3.5" bay adapter. This means no cardreader + floppy setup, and if you have SCSI, SATA or a PCI PATA controller, you NEED a floppy to feed XP drivers during the first phase of installation.
2) No antivibration fan mounts I have no clue just how loud that case would be when loaded up with my gear, and I wasn't going to take a 20% restocking fee hit just to find out.
3) No additional 3.5" bay adapters or hard drive mounting cages available. This means I have to sandwich my raptor and two Hitachi 250-giggers into 4 bays, one hitachi right on top of the other
4) The USB header situation is just as I suspected - there are THREE mobo headers. This basically makes the cardreader comment irrelevant - no mobo will have FOUR USB headers (1 for cardreader, 3 for USB ports)
5) I cut my finger on the inside edge of the side panel. It still hurts.
Lastly, the sides of the case are NOT black, they're brushed aluminum. Large-minute production change by Coolermaster.
With the new LiLi having some fatal flaws, and the Coolermaster ultimately a flawed beast, it looks like the only high-performance option left is the Antec P160...
