I have an old PC that I recently re-upped with Debian (forget which one, the most recent version). Here are the specs:
P3 1.2 GHz
768 MB DDR2
80 GB 7200RPM HDD
Gigabit LAN
Is this sufficient for a TF2 dedicated server? My internet connection can definitely handle it and the server doesn't need to be huge, just fit some number of people.

We used to bring our EEE PC 701 (Celeron 900Mhz CPU) and use it as dedicated server to our small TF2 LAN parties. It hosted without any problem 12/14 clients.
In principle I can say that your hardware could be enough for your purpose. Just keep in mind to not invite too many people.
