Well, after many months of waiting I am finally officially in the club and made my order today.
Thanks to everyone on this thread. There is a wealth of good questions and knowledgeable and experienced answers in here.
So I thought a well framed answer to the following power efficiency MOD questions would be helpful to us all new and old.
1. Existing Power Supply is loud and inefficient for our purposes: So with an up front detailed MOD of this thread in the first post it is assumed that you will reduce and improve efficiency. The efficiency improvements are not highlighted in the MOD just the "how to" part. Is 750W for a 24 drive config the correct target? Also, what is anyone's experience in payback on such a MOD? There is random data in the thread, but a targeted response to this question might be helpful as a summary.
2. Also, I read some things regarding RAM configuration: What is the best RAM config for a simple NAS with this box with the goal of reducing power consumption? Is it worth thinking about?
3. I think the above are the two primary power efficiency MODs. Are there any more worth mentioning?
4. I think that is always good to compare current technology. I know this is a deal and solid server hardware. Is there a solution that really reduces power as far as CPU/MB. My guess is probably not since if you have 24 drives what is the point.
