searching embedded system

servas!

i'm searching an embedded system for some datalogging and temperaturecontrolling system, but cannot find anything useful :((

so i'd like to ask you, if you can point me to any system available. does anyone know an assembled system (i'm not interested in collecting modules together and assemble on my own) with:

maximum size 110x110x35 mm, the smaller, the better
low power
running a linux environment (need php-scripts)
USB Host for connecting about 3 devices
one RS232 would also be good to have
WLAN !
cheap, of course :))))

the most suitable i've found by now would be http://www.omtec.de/200/cgi-bin/artikel/12/, but isn't there something smaller with ARM-processors available????

ciao
H.
