New boxer, variety of questions

[kwal]

Hello, I have never multiboxed before, but I am interested in starting it, specially now the the RAF bonuses, I think now is the perfect time to jump in

1) I am unsure how many accounts I want to box.. so I will ask this question
How many accounts can I run off my current comp?
AMD Opteron 165 (Dual Core) oc to 2.6ghz
2 GB ram
8800gt
2x500 hdd

2)I am fairly certain there is no way to 5 box off this rig, so I may consider upgrading.. How does this rig sound?
Case: CM 690
MB: Asus P5Q Pro
CPU: Intel Q6600 Quad
VC: Visontek 4870 512MB GDDR5
RAM: OCZ Platinum DDR2-800 4x2GB
PS: Corsair CMPSU-620HX
Monitor: 1x 20.5" 1680x1050 Widescreen (current monitor) and ill buy 1x 22" 1680x1050 Widescreen (will promote this to main screen)
HDD: 1xSeagate 7200.11 SATA2 640GB .. I will also use one or two of my current HDDs in this rig

Anything you would switch out? This rig would be about $1600 after taxes and shipping... a bit higher then I would like to spend. (I am in canada)


3) Class selection
I dont like the idea of multi boxing the same characters. It means at level 70 I will 5 of the same type of chars.. what would I do with them?
I like the idea of mixing classes, I would think I would enjoy a group of
Paladin (nice buffs, heal, res, tank)
Shaman(For the mail type of gear)
Rogue
Warlock (This is what I would like to play as my main at 60, but I would probably play as the paladin to level everything up)
Mage (Not sure why this class, not sure what else I want to be, and having ports is always nice)
But the question is, how good is it to have a mix of classes? Clearly I would not be as good as playing 5 of the same type, but with leveling so fast does it really matter
I pick these classes cause most of these classes interest me, and plus almost every piece of gear that drops, will be good for one of these chars since I have every armor type.. but I am guessing setting up macros and what not will take A LOT more thought and careful planning then just having all the same class.

Anyways this is still in the planning stages, and not sure if I even want to do it (or how many accounts I want to multibox.. $75 a month is a fair bit of money for 5 boxing), but at the very minimum I am pretty sure I will be dual boxing (assuming my current rig can handle it)
