I want to ask your opinion about this desktop system :

Cpu : i5 760
Cpu cooler : i have several options here and very low noise is very important :
(option 1) : Scythe Mugen 2 Rev. B + 1 Nexus 120mm fan
(option 2) : Thermalright HR-02 + 1 Nexus 120mm fan
(option 3) : Cooler Master Hyper 212+ + 1 Nexus 120mm fan
Mother Board : i think i should buy an Asus lga1156 with many fan connectors so that i will be able to control all the fans in the case with SpeedFan software. All MB-s support 5-6 LAN-s ? .. as i intent to have 5-6 diffent internet connections from different ISP-s
Ram : 8Gb (2x4Gb) DDR3-SDRAM of whatever Ram with small CL i can find
Hdd : i have several options and low noise is again important :
(option 1) : Samsung Spinpoint F4 HD322GJ 320GB SATA 7200RPM
(option 2) : Samsung F2 EcoGreen
(option 3) : Seagate Barracuda 500 GB,5900rpm
Psu : Seasonic X-400 Fanless or SeaSonic X-460FL 460W Fanless (and i think they are modular too). I do not know if you can tell if this 2 Psu-s have compatibility with the other components
Case : i think i should need a bottom Psu case like Fractal R3 / Fractal Design R2 with Nexus 120mm fans which will be conected to the Asus MB. I think Fractal allows me for 5-6 Lan-cards..right ?
Video card : i think any very silent 512Mb card + silent cooler (with 1 fan i guess) should be enough for my needs. Which one of this options you think its the best :
(option 1) : Radeon HD4670 512MB GDDR3 from Sapphire/Asus/Gigabyte/Msi .. around $80
(option 2) : Radeon HD4770 512MB GDDR5 from His/Msi/Asus/Gigabyte/Saphire..around $129
(option 3) : GeForce 9600 GT 512MB GDDR3 from Msi/Asus/Gigabyte/Evga/Zotac/Gainward .. around $106

I will not over-clock any component from the system and i will not play in any game that needs any very good Video card. But the pc will have several virtual machines installed and will run many hours per day and i need it very stable and also very silent. I wait for your advices. Thank's

Not sure what you're trying to do here.

1. Fill out the form in sticky, link in my sig.
2. If your main concern is virtual machines then go for a hyperthreaded CPU. i7 line, or the xeon 3440 if you can't afford one. Alternative is wait 2 months and grab i7-2600k.
3. You can't actually control all the case fans with the mobo if you have a bunch. Well technically you could use splitter cables and connect them to the same pin on the mobo, but then you'd need to make sure all are same model/RPM. Normally though, you just get a fan controller to handle this.
4. Mobo's usually only support a single LAN connection. Higher end ones like custom builders use support 2, however, it's usually 1 for ISP connection 1 for the actual local network. Why do you need 5 ISP connections?
I think win 7 will allow up to 2 ISP connections at once, more probably requires Server. Besides that, you also need to worry about network load balancing and the proprietary and expensive software used to manage that.
5. Best HD option would actually be a spinpoint F3. The Seagate will work though if it's 7200.12.
6. PSU either is fine.
7. Not too sure how to help you with case, I've never done 5 LAN connections outside a server cluster.
8. 5570 is another potential choice for GPU. They're low profile and you can get fanless ones.

CPU => Virtual machines like physical cores more than hyperthreads. Either the I5 760 or I5 2600k would be great, but don't overlook the Phenom II X6 for its six cores.

CPU Cooler => Either Intel LGA1156, LGA1155 or AM3 => CM Hyper 212+

HDD => Samsung Spinpoint F3 1TB or Hitachi 5K3000 2TB SATA 6.0 (currently $80)

GPU => HD 5570

1. Option 1 on the cooler, the SCMG 2100 is the no. 2 performer on the newer CPU's
http://benchmarkreviews.com/index.php?option=com_conten...

2. ASUS P7P55 WS SuperComputer with NF200 (has two LAN ports)
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Tho, I'd agree on a 1366 based system, choosing among the following:

http://www.newegg.com/Product/Productcompare.aspx?Submi...|13-131-642^13-131-642-TS%2C13-131-358^13-131-358-TS%2C13-131-665^13-131-665-TS

Check the MoBos here for the Manuals so ya can fiond out how many chassis fans the MoBo supports

http://support.asus.com/download/Download.aspx?SLanguag...

You can easily control all the fan speeds on the MoBo with the BIOS, no need for speedfan. From experience I can tell you that the R3E has 8 fan connectors: 1 CPU, 1 PWR, 3 chassis and 3 optional. That would easily allow you to control 6 chassis fans via the BIOS w/o doubling up on any ... The Sabertooth has 3 which can easily be doubled up on w/ 0.34 amp fans.

3. Two sets of 3 x 2GB CAS 6 .... $GB modules will be lower CAS
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

4. 5900 rpm drives get lower noise but performance suffers. The low noise / low heat selection among 7200 rpm drives is the Seagate 7200.12

http://www.tomshardware.com/charts/2009-3.5-desktop-har...[2371]=on&prod[3016]=on&prod[2365]=on

Looks like THG's charts are broken ... at least I am not seeing the column headings ...but Seagate leads by considerable margin in both noise and temperature.

5. All cards listed are DX10....for $10 more, move to a DX11 card (GTX 460)

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

6. Grab an SSD, Vertex 2 120GB
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

7. Looking at the reviews, the Fractal cases are quiet but run a bit hot. The 400w PSU's may be a bit light . See this link for silent PSU's

http://www.silentpcreview.com/Recommended_PSUs

For quiet builds, I generally go for the Antec P193
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

It's way oversized, not that that's a bad thing considering its price, but the CP-850's was even quieter than fanless models.

http://www.silentpcreview.com/article971-page6.html

Quote:
The noise level at startup was inaudible at 12 dBA@1m, at least from one meter distance. Only within about 6" of the unit could the fan or any electronic noise be heard. Amazingly, this sound level was maintained all the way to over 200W load. This is about as quiet as the Nexus Value 430 at low load, but the CP-850 maintains the low noise to a much higher power load, like the Seasonic M12D-850, 14 dBA@1m to over 300W.


Considering that the CP-850 is $110 and the Nexus Fanless is $130 / 150 worthy of consideration in case ya need the power someday.

I will have 6 virtual machines installed and i want each one of them to have its own IP address so i thought one option can be to have 6 Ethernet Lan cards, each one coresponding to a different Isp connection. Is this option good ?
Each virtual machine will have around 10Gb disk space..so 60Gb will be enough for all of them.I will give each virtual machine 1Gb of Ram memory..so 6Gb of Ram will be enough for all of them so having 8Gb of Ram + 1hdd (even with 320Gb) should be ok ?
Beside what i wrote above..i want my desktop to be as quite as posible (i will not play any game that will require any good video card..and i will not overclock any component..so 400W..or 460W seasonic Psu should be enough ?)

In my country this Gpu is around $200 and i do not think i need such a good card

400w seasonic PSU is fine.
RAM you'll want 8gb simply because of dual channel memory outside of x58. HD wise just get a 500gb. It's cheap enough to be inconsequential.

RE: IP addresses, I'm not a networking specialist, but quick call to them and their
response is that your idea won't work. You assign IP's to VM through software not hardware.

Use port forwarding and static Ip's to accomplish this.

When using a Virtualization you can set the software to bridge the physical networking adapter with the virtual one. On each of those Virtualized OS' you set a static IP address and for the software running you set up a deamon for a specific port.

For example, you can set one VM to port 22222, another to 222223, then use router to port forward the IP to the port you assigned to the deamon.

Best bet would be to read up on the VM software you use and see their directions.

Sorry..R3E is a motherboard ?

Here are some updates :

Cpu : Because i will use the pc mostly for running 6 virtual machines maybe i should change my choice from i5 760 (around $244) to one of this 2 :
Intel i7-950 with FCLGA1366 socket supported (around $360) and suports maximum ddr3 1066 Ram
Intel i7-870 with LGA1156 socket supported (around $349) and suports maximum ddr3 1333 Ram
Which one of the 2 i7 Cpu-s you think is better (maybe motherboard compatibility is important here too ?..and i do not intend to overclock it) The difference in dealing with (6 virtual machines + main operating system) between the i5 and any of the i7 justify this price differences of $105 and $116 ?

Cpu cooler : Scythe Mugen 2 Rev. B + Thermal Paste: Arctic Cooling MX-2 4g
Is ok this thermal paste ?

Mother Board : a FLGA 1366 or LGA1156 with at least 2 Pci slots (for my Nics)

Ram : i want 8Gb ddr3-sdram and it will be better to have 2x4Gb or 4x2Gb ?

Hdd : i want a hard disk of at least 7200rpm and because the pc wil run many hours/day it will be a good idea to buy a SAS and not a SATA hdd ? ( http://www.intel.com/support/motherboards/server/sb/CS-... ) Some options :
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Psu : i think 650W should be more than enough. Options : SeaSonic x-650 / Antec TP-650 / Corsair HX650

Case : Fractal Design Define R3 Titanium Grey. It can have 7 total fans. Do you think it will be overkill if i put 6 fans ? (i will let just 1 top 140mm fan and not 2). This way i guess i will have 3 in-take fans and 3 exhaust fans although i am not sure if the side-panel fan is for exhaust. The case comes also with a Fan controller for 3 fans

Fan controller : Scythe Kaze Server. The fan controller is a must-have ? .. the Fractal case comese with a fan controller for 3 fans

Video card : Asus Radeon HD6850 1024MB DDR5 DirectCU or maybe i should look for a Gpu that exhaust the hot air out of the case and not inside ?

Thank's
!
