Well, as I can't see the case, I can comment on two of the best cases I've used -
Antec's SLK3700AMB and
Enlight's 7237.
Pros and cons of each:
SLK3700AMB:
Pros
- Good finish
- Good airflow design - one 120mm each in front and back. Maybe it could use another intake though to help maintain positive pressure to keep dust out. And speaking of dust:
- Filtered intake
- Easy-open side panel
- Thumbscrews
- Cooled internal hard drive cage, which also slides out fairly easily
- Drive rails
- 4 LED's - Power, HDD, and 2 others
- Supports long cards (Promise SX4000) (Note: caveat below)
- Front USB ports
Cons
- The drive rails are much thinner than the Enlight's, and so they don't attach quite right all the time
- Fan clips instead of good old reliable screws. This means that if you want to slice the stamped fan grilles out, you can't attach your own grille to the outside.
- The front HDD LED's lead to connectors that all simply say "HDD LED" with no indication of which wire leads to which LED.
- It doesn't support "full-length" cards
- Top panel is riveted in place. Modding it thus requires drilling out the rivets before assembly - or else you need to empty out the case of all components if you decide to mod later, unless you want metal dust covering everything.
7237
Pros
- Nice case, easily moddable.
- Drive rails that seem to work with a variety of components
- It was a great case back in its day
Cons
- Top panel is riveted in place on this one too
- Not enough internal expansion bays for big RAID setups
- Should really use 120mm fans instead of little 80mm things
- No front USB ports
- Just doesn't have all the snazzy things that new cases come with, like those neat latches that the SLK3700 has for the side panel
So there, that's my list of likes and dislikes in my cases thus far. Now just integrate it all into your case design, and I'm sure it'll be perfect for everyone in the world.
To sum it up though, things I want to see:
No fan clips
Good airflow without needing the air-pushing ability of a standard 737
Front USB/Firewire
Wide drive rails to ensure compatibility with many devices
Screw on/off top panel, not riveted
Lots of room for expansion
Looks like you got some of that with the 6 3.5" bays and the 4 5.25"; do see about allowing a full-length PCI card though. I believe the Promise SX6000 is full-length. All those 3.5" bays are begging for a 6-drive RAID configuration.
I'll withhold further judgment though until I see a pic of this creation.
