I am building this computer for my work. The primary function will be capturing 40 minute to 1 hour worth of programming feed from a 3 camera/switched HD video studio; "sweetening" it (color correction, audio tweaks, etc.); bundling in pre-built graphic content; then rending out a final product in multiple formats....all in less than 12 hours.
I'm a bit worried about heat sink/mobo/processor/case compatibility. Also looking for ways to trim w/o compromising the timetable mentioned above. I've spent a bit of time researching these parts. I'm looking to those more knowledgeable to point out any conflicts. Alternate component suggestions are also welcome but vague "their better" reasoning won't carry any weight.
Thank you all in advance.
ADDITIONAL HARDWARE ON-SITE:
Blackmagic Multibridge Pro (for interfacing with studio) PCI-E 4x break out box
16TB (max, currently 2TB mirrored) NAS for archiving video assets (connected via dual 10/100/1000 ethernet)
Multiple Calibrated NTSC CRT Monitors and large format LCDs for review
The problem with going 3x4GB (other than the price premium) is that I have to populate two separate channel groups (one for each processor). So the 6x2GB would go 0-1a, 0-2a, 0-3a and 1-1a, 2-1a, 3-1a. With the 3x4GB I would have to choose which proc got two dimms and I'm not sure that would work.
It's only a small niggle - but the motherboard mounted in the case has the 24pin power and dual 8pin CPU power connectors at the top of the case while the power supply is on the bottom. You can route the power cables behind the MB and through the cable management cutouts to get around that I should think.
Can't see any other MB/HSF/CPU/Case issues. Thats a great case with plenty of room and cooling. Pretty quiet as well.
Thanks for pointing that out. I had seen some issues in the comments section of other components on newegg that talked about cable reach, etc. and I know that that particular board is tricky to install in most cases. The Mobo manual doesn't give detailed dimensions or clearances so it's good to here positive things about the case.
With the GPU on-board fan, the two fan/heatsink combos and the 4 case mounted fans I hope to have adequate cooling even during high-demand rendering sessions. Any thoughts/opinions?
The cooling should be fine, the CPUs, if not overclocked and with aftermarket coolers, will stay pretty cool. Those components are designed for servers so heat is a big consideration, you can see that in the 95W design. The biggest heat source in there is the GPU. The new fermi chips are notorious for running very hot, but in a big, well ventilated case like the Cosmos, it should be alright.
One thing I would like to point out is hard drive selection. Have you thought about SSD? For an OS/Apps/Scratch drive, you would see noticeable performance increases. Additionally, those Caviar Black drives are a bit outdated, and newer models like the Samsung Spinpoint F3 and Seagate 7200.12, are faster and quieter, due to the single 500GB platter design. Food for thought.
The 126mm height of the two HSFs is far shorter than the huge 162mm heatsinks that are known to fit inside the Cosmos.
I eye-balled the height above board and reach past socket of the CPU HSF looking for possible issue with clearing the RAM socket. It doesnt seem as it will be a problem with the low profile OCZ RAM modules. And if you reversed the heatsink & fan (or attached the fan to the opposite side) there would be no issue, except possibly at the top socket vs the PSU->MB power connectors.
Case cooling should be top notch, and still quite unlike a lot of server cases.
I went ahead and selected one of your answers as "best response." Thanks for taking the time to look into this issue that was a real concern for me. Nothing undermines credibility at my work like spending money on a solution that doesn't work (I know, we are talking a pair of $60 components but it is the down time they would cause).
I looked at SSDs and got sticker shock. I have never seen latency in the response of my applications that I couldn't attribute to something other than the system trying to access application data. I will look at the hard drive situation again though. It honestly received little attention from me this time out as I was relying on prior research.
