Monitor / tower related inquiry..

Greetings,

As a preface, let me say I know little about computer hardware, and after browsing the forums here and the wiki, I've decided software is the more 'me' way to dual box. I've glanced around, and it seems my tower is more than capable of handling two WoW accounts running at once, but I'd like feedback anyway, if possible.

I'm reasonably new to multi-boxing - though through the use of keyclone, I did get my dual wow accounts up and going, and got about a half hour of AWESOME-TASTIC-LOVE going on, until my head hurt too much to keep staring at the tiny secondary screen on my monitor (it's ACR Acer AL1916W [Monitor] (19.1"vis, s/n ETL5209005) and that isn't wide enough to happily situate the two screens to my liking)

So, I went out and got my hands on my old monitor that I had loaned to my little sister, who proceeded to spill soda on her tower and not need a monitor!

But now, I need to know, is it worth my putting the time and effort into getting my new-old monitor set up to my tower? It's a used tower, with.. Decent stuff.. I use it to surf the net and play WoW. It's not my ideal computer, but as stated - I know too little about hardware to build my own, and this one was less than $300 and he tossed in the video card and 50GB bigger HD than he was selling with the tower and a new CD/DVD drive along with an extra 2GB ram. Some specs, as provided by Belarc -

Hard drive - I know it's really small - but I had a huge HD in my last tower, and never ever used the space, and... I -was- on a tighter budget

* I completely understand I need to get a new video card to use two monitors. I simply list it as a mater of course.
