I guess I should have been explicit and stated I was looking for a comparable system that competes with the soekris. Does the dell t20 really count as competition to a soekris? A quad port intel NIC and a Dell T20 w/ Xeon is at least twice as much as this soekris. And then there is the whole issue of size:
It depends on whether one also needs a NAS with RAID disks, or a Windows desktop, or a media server, or a personal cloud. If you need any of those, then there is nearly zero marginal size or cost to add a router VM, with more hardware headroom and OS flexibility than a special-purpose router.
