I have quantum fiber and am using a Dynalink WRX36 running OpenWrt. Needed the vlan 201 configuration but works well.
OpenWrt is pretty amazing, my router downloads torrents, blocks ads, runs a VPN client (enabled per-device) for watching geo-blocked streaming, serves content from a USB drive to my TV, among other things.
I use a Dell R530 rack mount server. I had to configure PPP over Ethernet, and a Vlan of 201, but I've not been forced to the "quantum" BS. I've heard you just do DHCP, No PPPoE for that.
