I ran an old Thinkpad as a home router and small home server/NAS device for quite a long time, usually swapping out my old work upgrades every 3 years or so.

They all had onboard gige so it worked fine - native vlan for the inbound Comcast connection, tagged vlans out to a switch for the various LAN connections.

They were from the era of DVD drives so I was able to put an extra HDD in the DVD slot to expand storage with. One model even had a eSATA port.

They worked great. Built-in UPS and they come with a reliable crash cart built-in!
