RAID... http://en.wikipedia.org/wiki/RAID Read up, and enjoy
You must understand that, as experienced system builders, we know what's good and what er... isn't. For example, your question above about a 430W PSU being "enough"... well yes it would be, if it was a high-quality PSU. We recommend top-quality parts because we know that's what lasts. I'm truly sick and tired of cheap parts not lasting. I've had cheap PSUs fail on me, taking out the RAM and motherboard with it. I've seen (and fixed) other computers where the PSU has died, leaving nothing but the DVD burner in working order - yes, even the Hard Drive was blown and would not work.
Truly, you do not want this to happen to you.
Basically, that Cyberpower PC link is a basic system at a basic price. The only reason I wouldn't touch it at all, is because it uses a generic PSU. It is never worth it, in my opinion, to use a cheap PSU. The last thing you want (or need), is a great system turned into a doorstopper because the PSU fails.
Just my small rant, it's fine to question and learn, but don't forget we are volunteers here and only offering our experience. We don't do this pitch to "make a sale", we do it because we've "been there, done that" and truly want the best for you.
I understand that your not here to "make a sale" and I honestly do appreciate all the advice and suggestions that everyone has been giving me. Overall building my own computer just sounds like a very enjoyable experience but I also want to make sure that I'm not paying to much for what I'm getting. As I said in my first post I originally bought a laptop from my local Bestbuy store and I got what I now believe is a bad deal and I'm determined to not let that happen again. I apologize for all the questions but I would like to understand the system parts as best I can so that if I do build my own I know more about it if I ever need to upgrade or fix it.
As for my question specifically about the PSU, I didn't see anywhere on the part specifications that it gave a suggested wattage. Obviously I had no idea what the suggested output for these parts were and I need to better understand this system if possible.
Also do you have to use RAID if you dont use more then one hard drive?
No you do not have to use RAID at all, I never do.
The power supply thing is something over time you will know what to look at and generally know what brand / models are good and what is not.
The cheap priced units generally are not any good at all. It just depends on the brand, wattage, model, amps on the rails etc.. Almost always the included power supplies with cases are nothing but bad and they do not put out even close to what they say. They are made with cheap internals and can burn out any day of the week and also take out certain hardware in your pc such as the mobo, cpu, video card etc.. You always want to make a good SOLID PSU a top priority.
Example scenario: say you found a case for $30 (budget reasons) and you like the looks of it which that is fine if you want a cheap case but lets say it includes a 500W power supply with the price. That psu will be the biggest POS ever. 500w my @ss and think about it you are only paying $30 for the case how much would that power supply actually cost? Probably a $15 unit and that is very very very very bad. Big no no! LOL
See what we mean now?
I can generally just look at the PSU and tell you even without looking at the sticker/specs if it is good or not (mostly because I have already researched them). If it is a cheaper unit than the rest in a certain price range/ watt range and it looks all pretty with tons of lights and glow in the dark buttons etc generally that will tell you to STOP and do not buy it. Just because it is all flashy with tons of lights and glow in the dark buttons and cords + lets say $40 cheaper than the normal going rate/price on that wattage level It does not mean it is a good DEAL, it means it is trash. Lights are fine in power supplies I do not want to get you confused as you will just have to learn over time or just ask someone that KNOWS what is good.
Like troy said we aren't like the people at bestbuy, dell, gateway, hp etc that will tell you anything just to make a sell. It is different here, we don't get any money from you or anyone. We work for FREE as volunteers.
