Hi, I have 3 questions!

1- How many slots would this VPS handle?

VPS Software: OpenVZ/vePortal
CPU: 2.000MHz
Memory: 512MB Guranteed / 1GB Burstable
Bandwidth: 2000GB (1gbps Link)

Also I would like to run JTS3ServerMod.

2- I'm new on linux do you recommend centos, debian or ubuntu for newbies?

3- 32bits or 64bits?
