Joe, I think you should stick to what you've got, and try to improve on it.
More reviews, more articles, more roundups, writers who write
but please, for the love of god, stay away from the case mod DB! You'll just end up attracting the wrong crowd...
pHaestus upcoming roundup should be very exciting.
I'd like to see more DIY articles on watercooling and something on phase change, home-made! I'd also like to see more theory ('cause u know, i'm the calculating type...)
You might do well by attracting/rewarding users to write/contribute something.
