Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I will be reusing 500gb Harddrive, OS, DVDRW, and 19" LCD Monitor with this. Not really looking to overclock it. This is the best I could come up with by staring at the wonderful egg for about an hour. Keeping it below 500, the cheaper the better
The build, as a whole looks fine. The instant savings that you receive on those bundle deals makes "optimizing" it for less than what you've already done very difficult.
Some people would tell you to go with a "better" motherboard, like the Gigabyte GA-EP43-DS3L or the MSI P43 Neo3-F. But if you're not planning on overclocking anything, the Biostar TP43D2A7 should be good enough for your needs. (I haven't found many reviews on it, so I can't vouch for or against it.)
The one "flaw," if you could even call it that, is with the Antec Three Hundred case. However, two of the three places that have it for less (specifically, Amazon and Buy.com) are out of stock at the moment. Compare the total NewEgg costs of the 300, including shipping, with the total costs from Provantage (which has it for much less, before shipping, than NewEgg) and stick with the cheaper place.
Overall it looks fine to me. With the combo savings and instant rebates, I really don't see anything to optimize. The only thing you may be able to optimize is the video card, but the 8800 GT is still a solid choice for a budget system.
