The Cavalier is essentially the same case as the Centurion 5, but with a different Bezel. Of those two, I prefer the Centurion because I don't like the 5.25" Drive Bay Doors. Unfortunately, both cases lack some features that I think are very nice:
1. No rubber grommets for HDD mounting
2. The PCI slot covers are punch out and not easily replaced
3. Only one External 3.5" Drive bay
The wavemaster looks pretty cool, but has a drive bay door and does not have HDD grommets. Therefore, I don't really like either the Cavalier or the Wavemaster, and I marginally prefer the Centurion 5. I think the Centruion 5 looks very, very good, but I'm dissapointed that it's missing the HDD grommets (I could work around the other negatives)
-D'oh!
