It's just an experiment, but who knows :)

This is for a small office of 30 people - only 10 channels of the PRI are 
"lit". The TDM card is for outgoing calls to a 2-port Premicell unit 
(analogue GSM adapter with LCR to mobile phones) and for 2 fax machines - 
which is the only thing I'm a shade concerend about - the analogue FAX 
through the TDM board and back out via the PRI board.. (incoming faxes are 
handled by spandsp/RxFAX and sent via email)

And this in only a mere 1.3GHz VIA board too. 384MB of free RAM (512 in 
total, but the OS lives in a 128MB ramdisk) No transcoding and everything 
is custom compiled/built. (Asterisk 1.2)

I actually wanted them to go for a Xorcom channel bank, as they have a 
door opener/bell-push to manage somehow too, but they weren't keen on it, 
and the Xorcom is a bit over kill - if only they did a 2+2 or even 4+4 
(FXO/FXS) unit rather than an 8+8 ... (or even a stand-alone IO port!)

I'll let you know how it fares :)
