I'm currently running the following as the Gateway/DNS/DHCP for the mid 
level startup (40 people) I work for.


I added 4gigs of ram and the cheapest SSD I could find.

It does inbound/outbound shaping on our 100/15Mbit link and when I slam 
the link with netperf-wrapper top tells me the cpu is about 30% used.

I don't have any log files but when I tested this box in-line on a GigE 
network I seem to remember it being able to do far above 100Mbit but I 
don't remember how much more.

It's running a custom build of BB.  Custom because the dual GigE network 
chipset is not recognised by by openwrt BB and I had make a small patch 
to fix that but every thing else is stock BB.  QOS is qos-scripts 
scripts and not a version of sqm-scripts.  When I got it all going I 
didn't full recognize that all the sqm stuff was not in qos-scripts.  It 
works and currently meets our needs so I've not felt much need to mess 
with it.

It has a PCI-E x1 slot so you could add a wireless adapter.

Sadly its out of stock now but there are probably plenty more options if 
we started looking for them.
