Final Build:

Only two issues:
DVDRW reused (not working now all of a sudden, wont open, not recognized by Vista, green power light is on)

Does anyone have any advice for making optical and hard drives quieter (mounting options, damping etc?)

ASUS Rampage II GENE LGA 1366 Intel X58 Micro ATX $209.99
i7 920 D0 stepping chip $212 after tax
Sapphire HD4670 $53.99 open box
OCZ Obsidian 6GB DDR3 1600 (PC3 12800) OCZ3OB1600LV6GK $99.99 after MIR
Western Digital 1TB Black $74
OCZ ModXStream Pro OCZ700MXSP 700W $69.99 after MIR
COOLER MASTER Elite 341 RC-341C-KKN1-GP Black Steel MicroATX Mid Tower $45.99
Scythe MUGEN-2 SCMG-2000 120mm Sleeve CPU Cooler $36.99
Scythe SY124010L free /w bundle (not sure how to use this one yet...)
Used the included thermal compound, OC 3.68 ghz (Turbo, all power saving features enabled) @ 1.354 volts @ 75C prime95, I'm going to drop it back a notch to keep it under 1.35V core.
Windows Vista Home Prem with free win7 64bit upgrade $139

Damn I went a little over budget...


I still need to get some more case fans and mount a second less than ~27dB fan to the CPU heatsink.
Scythe SY1225SL12M 120mm "Slipstream" ?
The loudest thing in my case right now is the hard drive even at 100% processor utilization.

Yep I managed to fit the Mugen 2 in that case, and with the fan mounted blowing air upward through the heatsink it completely exhausts through the rear case fan and the power supply. A second fan on the cpu pointing to the rear and an intake fan would surely drop temps substantially. On the plus side the passive GPU heatsink gets a ton of air blowing across it due to the mounting location of the mugen 2, I'm sure it will overclock much better than an average 4670 with a noisy fan. I'll get some pictures up eventually


Old First Post Follows:

This is my first build since socket A so a lot has changed and I would highly appreciate some advice.
I know this is a very tight budget (less is always better) for socket 1336 but the primary use will be for low noise, compact footprint number crunching and I'm aiming for a safe ~3.6 ghz overclocking. The goal is to have the most upgradeable system possible so that I just have to drop in an i9/i11 (or whatever the max 1366 chip for this generation of motherboard is) in 2-3 years and upgrade the graphics card as needed. This computer will reserve the second x16 slot for USB 3.0 *if* it ever comes out.

Current selection:

ASUS Rampage II GENE LGA 1366 Intel X58 Micro ATX $209.99
i7 920 D0 stepping chip $212 after tax
POWERCOLOR SCS3 AX4650 512MD2-S3 Radeon HD 4650 $41.99 after MIR
OCZ Obsidian 6GB DDR3 1600 (PC3 12800) OCZ3OB1600LV6GK $99.99 after MIR
Western Digital Caviar Green WD7500AADS 750GB $69
OCZ ModXStream Pro OCZ700MXSP 700W $69.99 after MIR
or CORSAIR CMPSU-750TX 750W $99.99 after MIR

COOLER MASTER Elite 341 RC-341C-KKN1-GP Black Steel MicroATX Mid Tower $39.99
Scythe MUGEN-2 SCMG-2000 120mm Sleeve CPU Cooler $36.99
Scythe SY124010L free /w bundle
Scythe SY1225SL12M 120mm "Slipstream" + AS5 thermal compound bundle $20.98


I'm having a tough time finding out if any small case exists that supports a fairly normal overclocking fan and heatsink. I would really appreciate advice with respect to this issue. I would consider going to a small ATX format case (possibly board too) if this is an unlikely proposition.

I'm sure the first words out of most peoples mouths will be in bold *get a better video card*. I'm open to sub $100 suggestions with less than 24dB under load fan noise and HDCP HDMI 7.1 LPCM audio pass. The initial thought for the powercolor card was silence, cheapness, and reasonable 3D rendering.

P.S. I already have the i7 920 chip.
The main OS will be linux and this is a first time for me, any guidance is welcome.

Thanks and Best Regards! :hello:

change the caviar green to a caviar black, change the mugen 2 to a spire thermax 2

other than that, nice build

Thanks for the advice particularly for pointing out that fan to me. Does anyone know a way to safely slow down a cpu fan via undervolting or other method slightly ~(20%). 36dB is likely quiet enough but just in case :o  its good to have options.

Could you break down the differences between the black and green WD a little more?


EDIT:
I did a little more homework on the fans
http://www.xbitlabs.com/articles/coolers/display/core-i...
http://www.frostytech.com/articleview.cfm?articleid=234...

Using the Coolermaster V8 and Thermalright Ultra-120 as benchmarks that span the two test batches its safe to say the Mugen 2 seems to be about in line with
the noise levels seem to be 12-16dB quieter with the xbitlab procedure than frosty procedure due to placement and conditions.

I'm going to conclude that the mugen 2 is about 10dB quieter on high than the Thermax II on high with nearly identical thermal results. I do have to conclude that both fans are going to be very quiet on lower settings though and the thermax2 seems very easy to control so its a hard decision! Does anyone know if there are options to control the mugen 2 other than in bios? It will take up to 4 fans so I am leaning in the direction of the mugen right now.

you could try a fan conmtroler, but i always hated those things
