Help Plan My Rig

[Llamaduck]

Greetings,

Let me preface this by saying I'm -not- very hardware savvy - most of my computer know-how is software related, and that won't be changing in the near future. This means that things like overclocking and liquid cooled systems are probably out of my depth - if something breaks once I've started using it, fixing it generally means being without my computer while it's away being repaired at high cost - and I'd like to avoid this. With this in mind..

Buying a computer straight off the shelf is a bad idea. I know this. It's cool for writing emails and spreadsheets, but it's not a gaming standard - so for my next computer, I'd like to get something put together. Seeing as how I have no idea what I'm doing (well, very little of one) I'd planned to go to Memory Express. Some extensive Googling says they're the best comp shop in my area. But just because I'm paying someone to build a computer for me doesn't mean I trust 'em to get it the way I'll need it - especially given that I wouldn't understand if they used the specs to explain they'd just inserted a hamster wheel in place of a fan.

tl;dr?

I want a rig that'll let me dual box (two) with high graphic settings on on my main toon. I'm thinking three monitors (one for main toon, one for alternate toon, one for non-gaming applications like Skype, wowhead, ect) and don't intend to run more than two toons at once - a single main and alternate. This is largely because I've already got monthly fees from another game, and don't really feel like paying for more than one extra account.

I don't -technically- have a budget, since I'm basically stuck saving up money anyway, so I can save less or more until I get what I need - but I'd love to spend less. Any help would be appreciated.
