Install a Mystic's Cubic Chunks Modpack server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → Mystic's Cubic Chunks Modpack)
Great serverhost. I love the dedicated proxy plan which allows me to spend less then I would need to on other hosts.
Everything was fairly painless and a breeze to set up. I'd go with scalacube again and again.
My only gripe is the minor inconvenience of using custom server software, I would love an option for "custom" when creating a game server.
It's also strange how there isn't an option for velocity but there is an option for cauldron which isn't even maintained anymore..
