Hamachi Minecraft Server

So... I posted this thread because I just made a test server on my PC and I am using Hamachi as a virtual LAN and I want to see if anyone could help me build it up until I can get my Server bought and to get my router port forwarded.

Specs: (These are a bit crap because I have really bad internet that I am going to fix)
Ram:3.5Gb Dedicated RAM
CPU: Quad-Core AMD 1.8Ghz Processor
Hard Drive: I am allowing up to 200Gb of Hard Disk because I don't really know what is ideal
Network: KC Communications (7.5Mbs UP, 3.525Mbs Down)
SlotsIt will say 20 on the Server but I only have 4 other available other connections for Hamichi)
Other Info: I have disabled the nether because I have a feeling that will slow the server down having multiple servers running but depending on how popular the server will be I will add multiple servers and higher specs.

If you want to come on this Server please tell me on Skype: Theo Sheovelot

Also... You will be staff while the server is up early and you must know what you are doing.

Hamachi Information:
ID:SmileyManGaning
Password: None!
IV4IP:25.181.117.207
Minecraft:1.6.4 (Because that is easy to run on Hamachi for some reason)

Thank you for reading

Plus It won't be on for a couple of days.
