Note that I've seen people running gnome on a netbook.
Still, I see this, and I think more about: "backups", "configuration management", "shell access", "VPN to other more powerful dedicated servers in OVH", "personal storage", "scheduled tasks", "monitoring systems", "status pages", etc...
The price is nothing, I still ask myself if it's rentable because "it's an Atom" and changes the power bill, or this is more a unprofitable product to attract you to other products.
Lets say 3€ * 12m = 36€ year, It takes some years to recover the hardware costs (without count electricity bills, company salaries, connectivity, taxes, etc).
