Looking for advice on my computer build

[Max-Powers]

1) What will you be doing with this PC? Gaming? Photoshop? Web browsing? etc
I will be using this computer as a HTPC and gaming machine. Gaming on 1080p LCD TV. Because gaming requires more power than HTPC, if I can game, the HTPC aspect only requires some outputs like spdif and HDMI, a TV tuner, and I should be good on HTPC hardware. I just want to make sure there is no problem gaming using this setup on 1080p.
I will never play crysis!! Fallout 3, Left 4 Dead, orange box, CnC and such. My main concerns are noise, heat, and will it fit in my case. I will be sitting 6'' away and am not too picky.
2) What's your budget? Are tax and shipping included?
My budget is ~$1000 but I can go over without it hurting my feelings.
3) Where do you live?
Austin TX 78717
4) What exact parts do you need for that budget? CPU, RAM, case, etc. Please be very specific.
Everything including TV tuner which I will choose at a later time. Still looking.
6) Will you be overclocking?
I do not plan on overclocking.
7) What size monitor do you have and/or plan to have?
I plan to have a 42''+ LCD TV at 1080p
8) When do you plan on building/buying the PC?
I will build it in July
9) What features do you need in a motherboard? RAID? Firewire? Crossfire or SLI support? etc.
No crossfire. I want good onboard sound. I want Firewire and spdif
10) Do you already have a legit and reusable/transferable OS key/license?
I have a Vista. The basic Vista that would come with a dell computer. I hear the 32 bit Vista only supports 3.5 gig of RAM. Is this true? If so, I will need to buy Vista 64.

As I explained above, I want a gaming rig that I will also use as a HTPC in of course a HTPC case. Here is what I have so far. I am going with an intel build.
Case: LC20B-M
Or the Antec Fusion Remote Max. With the LC20 I will have to buy the case fans which I don't mind. Has good reviews and should suite my needs if everything fits. One question is, what are some good 80mm case fans? The Remote Max is big enough and has great reviews, but it is just so huge.
Motherboard: GIGABYTE GA-EP45-UD3R
I chose this mobo because it had many ports and seemed to get decent ratings. Onboard sound will be going to a Denon 1909 and then to a Energy speaker setup.
CPU: E7500
This is dual core. The quad core is just too expensive and I am not going to hardcore game.
CPU Cooling: Noctua NH-U9B
No real reason why I picked this one. It was suggested to me. I wont overclock so all I need is something that is quiet and can move air around.
Video Card: GIGABYTE Radeon HD 4850 1GB
This is passively cooled. I want it to be quiet. I am willing to change my choice on this if I can be convinced. I dont want anything faster. My concern with this is if it will fit in my case. I will also need air to move around within the case fairly well. I don't do hardcore gaming, so it shouldn't get too hot. Had good reviews from what I have read.
Memory: some OCZ Reapers 2x 2gig (4 gig)
Clueless here. I know nothing about memory. Picked these because I hear OCZ is great and this one had the little award thing next to it =) But The little scythe bullcrap looking thing worries me. Why is it there? Will it mess up anything? Will it stick up too much? I can just go with whatever; OCZ had some purdy
Power Supply: CORSAIR CMPSU-650TX 650W
I hear crosair has great power supplies. This one had a nice rebate and good reviews.



Anyway, what do you think? Any suggestions to exchanging parts?

*bump*
any thoughts? Still lacking a Blue Ray player and hard drives but I'm not too worried about that.

I hear the 32 bit Vista only supports 3.5 gig of RAM. Is this true? If so, I will need to buy Vista 64.

Yes, most 32bit OSes, including Linux, Vista, and XP, can use anywhere from 2.5GB to 3.5GB of RAM depending on the video card and other devices. If you want to use all 4GB of RAM, you will need to use a 64bit OS. If you're willing to reinstall the OS again in Q4, you could try out the Windows 7 RC. Pretty stable so far in my testing.

One question is, what are some good 80mm case fans?

Recommended quiet 80mm fans:

Horrible choice for the money. For just $10 more, you can get significantly faster quad-core CPU:
$270 - AMD Phenom II X4 940 CPU + Gigabyte GA-MA790X-UD4P AMD 790X AMD Motherboard Combo

However if you think quad-core is a bit overkill and you don't need all the features of the Gigabyte mobos, then I recommend this setup:
$174 - AMD Phenom II X3 710 CPU + Asus M3N78-VM Nvidia GeForce 8200 HDMI mATX AMD Motherboard

One of the neat features of the 8200 chipset is its support for hybrid-power. With hybrid-power, you can turn off the dedicated video card and use the onboard video and turn on the dedicated card when you want to game. This can be done with a mobo supporting hybrid power and a GPU that supports Hybrid-power. Speaking of GPU.....

Video Card: GIGABYTE Radeon HD 4850 1GB

Even if you don't do hardcore gaming, the video card can still get hot if there is insufficent airflow and the like. While I know you said you don't want anything faster, Silent PC Review found the GTX 260 card to be very quiet by their relatively high standards for silence and quiet. Considering that the GTX260 is only $5 more than the card you chose and offers significantly higher performance and supports hybrid power, I highly recommend getting the GTX260:
$170 - BFG Tech BFGEGTX260896OCE GeForce GTX 260 896MB PCI-E Video Card

Memory: some OCZ Reapers 2x 2gig (4 gig)

I think those heatsinks will interfere with the cooling and palcement of the CPU HSF. So I recommend getting this RAM instead:
$45 - Corsair TWIN2X4096-6400C5C2 x 2GB DDR2 800 RAM

$1,000 bucks you can do an Intel Q8400 Quad CPU + Mobo combo or an AMD Phenom II 940 Quad CPU + mobo combo build.

 

[PC_User]

For about $1,100 you can start thinking about an i7 build.

i7 920 - $280
ASUS P6T - $250
6GB DDR3 - $90
Corsair 750W - $120
WD 640GB Black - $70
Radeon 4890 - $235
Xigmatek S1283V - $40
DVD Burner - $25

TOTAL:$1,110 before taxes, shipping, rebates.

You can step the 4890 down to a GTX260 and save about $50. Can also save about $50 by going with a ASUS P6T SE or Gigabyte EX58-UD3R instead of the P6T.

It's too late right now and I'm too lazy to link everything.
