Is my computer capable of boxing 5 accts (looking to do 5v5 arena)

I recently found out about dual-boxing and I saw some videos on youtube on 5v5 arena box shaman and I thought it looked awesome to try. Is my computer capable to box though?

My laptop specs are:
Intel duo core2 t6670 @2.20ghz
4GB of RAM (although I'm running windows XP so it only shows as 3gb of ram)
Nvidia geforce 9300M GS

I'm looking to do boxing all on one computer, but I'm trying to figure out how to start. I haven't leveled my character, but was looking to start soon. I'm looking to try this on a 3.3.5a server first before doing it on retail (since it'd take a lot of time investment). Is boxing 5 shaman the easiest and best for my case? I've also seen 5v5 druid, but don't know how that goes.

I'm trying to box something that is easiest to play so that the learning curve won't be too high.

Is this something I could do? If so, could somebody lead me in the right direction on how to get started.

FYI I saw Aelli's vid online and it looked awesome.

Many questions to be answered, im going to try to answer a few of them.

1. Aellie is 4x shaman, not 5. He is playing with a healer friend in the movie.
2. You Laptop might be able to launch 4-5 wow apps, but i doubt it will be a pleasant play so to speak.
3. Shamans (ele) are pritty gimped atm and not that good, not saying it wont change, just that they are weak at this time in wow.
4. Id recommend as u describe testing it out first (both for the computers sake and for your own), tho i can not recommend private server but trial accounts, and try out some questing and get a feel for the boxing program of your chooise.
5. Melee teams are pritty populair atm but id say that a shaman team would be easyer to understand and play.

Use trial accounts, discussing private servers is a violation of the Rules
