So i recently setup a server network on my dedicated server and still have two slot open on my multicraft panel. There is a total of 12Gb of ram left to give to both of these extra slots.
The specs of the server are
Intel Xeon E3 1245v2 4 c/ 8 t 3.4 GHz+
12GB ram left after my network setup
250mbps internet connection
with at least 1Tb space
enough space for your server and backups

Panel is multicraft with ftp access with spigot and bungee jar already installed

Please Pm for more details.
