100Mbps EPIA EK8000 server here, with 2 diskless/deviceless clients. 
According to Munin, during a typical week :
* peak disk IO : 2k blocks read per second, 2k blocks written per second
* peak eth0 traffic : 10Mbps to the server, 15Mbps from the server
* 2% CPU due to the VDR server process
* 8% peak CPU due to DVB + eth devices during recordings or live-view
* 80MB memory for all userland apps (VDR + Samba + DNS + MPD, etc. etc.)
