update: 1k gaming rig close to purchase and need advice

Well, I don't see any major flaws. Actually I don't have much to offer for this one.

1. Yes, the RE is better than the SE is. Especially if you are going RAID. It also has the 16Mb cache.

2. Well Rosewill PSUs are generally considered garbage. I would probably avoid them if possible. It's hard to find a good PSU in that low of a price range,this is the best I can come up with (in 2 minutes that is..). I'm not sure how good it is, but it has enough power for this system.

3. That case is not too bad, especially for $27. Just remember though, 80mm fans are not as effective as the larger ones. Fortunately a $100 budget here gives us some possibilities. Here's a quick list I came up with with a quick search:
NZXT Apollo

Sunbeam Transformer

CM Mystique

And if you really want things cool:
Sigma Shark

4. Well if you are planning to OC, this RAM is probably good for you. If you are planning on some really hard core OCing, I would suggest using this since that mobo can support DDR2 1066. This is specifically on the supported Memory List as well.

That's all I have for suggestions/comments. Good Luck.

The more I think about it the more I worry the Rosewill psu will be a dud. The amps are pretty high but if it fails two days after the warranty I'm gonna be pretty po'ed. I need to stay within budget but I may have to bump up my psu allowance above what it is. I plan on expanding to at least three more hdd's and I have a 8800 gts 640 already so I'm gonna need some power. Not sli power, but still a good clip. I'm planning on ordering this weekend so any help figuring out what psu works best for me and my budget will be really appreciated.

Also, can I run a wd RE hdd as the only hdd until I can expand? I'm not sure I understand if the RE is worth it or not. Still, it's only a few bucks more than the SE so if there is any added benefit then I'll use it.

Thanks guys for your input on this thread and others. I purchased my new system on Thursday and it will be delivered on Tuesday. The only change I made was the power supply. I nuked the Rosewill psu in favor of the Mushkin 580w.

It's the advanced model so it has a "T" ranking which places it higher than the level 3 systems like Silverstone and Fortran. Mushkin is kinda new to the psu arena and I think they are really trying hard to make a name for themselves. They even replied to a review for this psu in which a customer got a dud. I haven't seen that before and was really impressed that they took the time to see on newegg what people thought about their psu's. My system priced out at about $1040 and I think it's a winner for the value received. If anyone wants to build a gaming rig for about $1000 I think in my humble opinion they should look at my component list.
