[Solved] New System Build: Please evaluate my 'Budget Gaming Computer'

I've picked out the parts (below) after reading the article on THG... "Building a Budget Gaming Machine." I substituted a couple items, and added an OS, since I'm building everything new from the ground up.

BEFORE I order anything, I will appreciate your time and experience in evaluating my list of parts and making recommendations that may either reduce the prices or increase the quality and functionality for this proposed system. My budget is very tight, and the "Budget Range" I listed below is maxed!

All advice will be appreciated. TIMELY REPLIES will be appreciated, too, because I feel I should order BEFORE the prices increase and/or the products will no longer be available!

Thanks in advance.

Larry

I'm really glad you mentioned the voltage issue! I wasn't aware of those important facts.

RAM COMPATIBILITY?
You didn't mention the motherboard I selected. In regards to that, I noticed that the RAM you suggest is only for "Dual Channel Intel Core i5 & Core i7 CPU for P55 motherboard."

I'm not sure, but I don't believe my motherboard selection is "P55". I'm further confused about it saying "Intel" when I've been looking at "AMD" CPU's. Those terms don't show up on the motherboard specifications. I don't even know what it means. Sorry. Please, can you explain this to me?

I'm confused because I don't know whether it will be compatible with the board I selected? Will each of your suggested parts be compatible with either my motherboard, and/or with all the other parts you suggested. Heh heh. I'm trying to be certain that everything will work together in the same system. Can you please clarify this for me?

EDITED: My mistake. I didn't read far enough down the page on NewEgg! Sorry.
I didn't see any useful specifications on that case as to how many bays, other features, etc. That kinda' leaves me wondering. I'll try going to the manufacturer and see if I can get more info on it.

Thanks again, for your help!

Thanks! I looked at the GIGABYTE boards. Both are good. I picked the DFI LANparty MB only because it was recommended in the "gaming build" on THG (by someone?) and I didn't know what else would be better. Had to start somewhere. Heh heh.

What ASUS MB would you recommend? I prefer them, (as I mentioned in my original post), but there are so many optional types and other considerations, it's confusing to choose the best one for my needs. I have been unable to find CURRENT reviews on THG about ASUS boards, especially when it comes to performance, upgradeability, compatibility, versus cost, etc.

I definitely like the overall price, compared to what I've been seeing from my other choices. You didn't list a video card, but there's enough savings for me to buy a decent ATI card, and possibly upgrade the PSU.

Personally, I've had wonderful experiences and never a problem with any of the ASUS boards I've had.

Thank you for providing the list of items. Very interesting. I read all the reviews on each of the items. Most were positive.

Thanks. Good feedback.

As I said, I've been looking and reading about everything you folks recommend. I still have some preferences of my own, like the Corsair PSU, and the Antec case. Well... I'll have to reconsider some of my choices because I found out that the Corsair PSU fan blows downwards! That won't work well in a case that mounts the PSU on the bottom of the case. I have yet to find out if the PSU can be inverted, but so far, even though it's rated extremely high, it seems like a stupid design. The same thing goes for whoever came up with the idea of putting PSU's on the floor of a case (ref: the Antec NINE HUNDRED TWO case) and many of the other newer cases. My brain is reeling already from all the technical decisions, and now this issue arises! Ha ha.

Without having the new PSU here, I wasn't exactly sure whether it could be turned upside down or not (screw holes, etc.). I'm glad it can be. That solves that issue.

Not to belabor the point, but the opposite of your description is equally true, and maybe even more efficient in removing heat.

Since by nature, heat rises, it accumulates in the top of the case. I have an older motherboard now and it has the CPU and RAM located at nearly the TOP of the case, immediate under and near the PSU.

Getting rid of that hot air quickly (via the exhaust fan on the PSU) prevents it from "pooling" and bathing the critical components. Simultaneously, it (the fan) is drawing in more cool air from other areas (mostly near the bottom of the case, since cooler air sinks). Thus, the cooler air is being pulled across the heated components on its way out of the case via the fan.

Both methods seem viable to me. But, in my "case," (pardon the pun!) it makes more sense to get rid of the hot air FASTER. There is no opening on the top of my case, therefore any cool air coming in from the bottom (PSU fan) would be merely mixing with the hot air already accumulated in the top of the case!

Of course, a better solution would be to have 2 fans, one at the bottom and the other at the top. Bottom one draws cool air inward... top one blows hot air out of the case.
