hmmm, can't use current case because its not mine, Cases are pretty expensive too, will push my budget up a bit. I can use my current CD drive though which is a plus. Can I use any case? Does the case matter alot? (as far as cooling and such)
You can generally pick up a cheap Mid tower for around $50 and under, cooling shouldn't really be a problem unless you live in the dessert.
oh and isn't 1.8GHz slower then 3.3? sorry I don't know much about this stuff. Should I buy that and overclock it? or is it actually better because its dual?
Yes this is slower, but the dual makes it faster because it has 2 cores to run information through. Also you can overclock it to make it x2 as good, maybe to around 2.8ghz.
Oh and I read the reviews of the power supply, it says its not really 400W its 350W should that matter to me?
The actual power isn't really a measurement of a power supply, its the 12v rail, this power supply is cheap and pretty decent, should be fine unless you want to upgrade in the future in which you may need a better one.
Sorry keep thinking of more crap, what about an Ethernet card and sound card? I just read about Dual Core, so basically I have two 1.8ghz with a dual core?
No problem questions are fine. Ethernet should come with your motherboard so it will have a little port which you can stick the cord into on the back of your case. A sound card is not necessary these days unless you have some hard core stereo system, on board sound these days is quit good. And the dual core thing i mentioned above, its kind of like having two cpus at 1.8ghz between them, your computer still runs at 1.8ghz but has two cpus to make calculations. Overclock it and you will be fine.
Sorry about all of the dumb question but.. on the motherboard site, what does the font typed in red mean?
It basically means that if your using a fsb1333 mhz cpu (which you are not) and you are using all the ram slots, the ram can become underclocked causing the computer to crash or be unstable.
Also, is it easy to build a computer? It should be a fun experience at least.
It is easy after a bit of experience, i wouldn't recommend diving in and just trying to build one because you could mess something up. Do you have any friends with computer building experience? Ask one for help or if worse comes to worse you could either get a store to do it for you or get a in depth computer building guide.
