Hello again,
Well, it seems everything is going to work out. Scan Computers tested all my components which are working, besides the fried motherboard. They are going to replace it, so I'll get everything back in perfect condition.
During this period I think I found out what happened with the mobo. It was all my mistake and this is mainly because I haven't built a system in years and I've forgotten a couple of things. 
Basically, I completely forgot about the standoffs and I screwed the motherboard directly to the PC case..WHICH shorted it out. Yes.. how stupid can you get. Well, lesson learned..the hard way, although I am lucky enough to get everything back.
Anyone knows a good "How to build a system step by step" guide? I really want to check if I am forgetting something...
