I'm planning on putting together a NAS box for work. We need it for 2 purposes: one, for the primary "hdd" for a linux cluster that runs FINE/turbo CFD software, as well as general storage for the office (academic setting).
It needs to be very high quality (in terms of fidelty and throughput), as CFD is a very intensive program with a lot of writes and reads with large amounts of data.
That being said, the build I put together I made with what I found from the free NAS guide as well as an old nas guide on the maxpc website, but you'll notice it's a super system, kind of. I feel weird building a system this good (the type you'd kill for at home) as a glorified HDD, but I think I might need something like this to get the performance I want, since I'm not exactly using it just to stream movies over a home server.

I would probably not buy from the places listed and would buy mostly from Microcenter or newegg (or amazon) whenever possible.
Here are my defenses, and tell me if you think I am wrong. I very well may be.
I'm starting off by thinking that I want a huge amount of storage, and will definitely need a large number of HDDs. I will be using at least 8 (4 TB each) to start, and I'd like to add as many as I can. That is the reason I am going with the huge case. It allows for 13 3.5" drives, and I can see using 12.
That is also why I want such a big motherboard- I need at least 12 sata ports.
Further, RAM is apparently a huge deal for NAS- recommended at least 1 GB per TB. I'm starting off with 32GB with the ability to double it (as I have 8 ram slots) down the road. We will probably start off with 8x4=32TB of HDD space, so this worked out well, but I need to be able to move up. 8 Gigs looks like the max ram per stick at this time.
That shoots me into the LGA2011 camp pretty quick. I chose the middle of the line processor. I do not know if I can use the cheaper 4 core, so I would like advice here. I believe that NAS uses a lot of parallel computing, but I don't know if it could possibly saturate this system, so there is one place I might be doing some overkill.
I'm using that exact cooler on my personal build right now, and I like it. I didn't at all enjoy the installation process on it, but it works great and isn't terribly noisy. If someone has a recommendation for something that is super quiet and efficient, I'm open to suggestions. As is, I know this will work well since I have experience with it.
I added a cheap video card so I can boot the thing and see the bios. As a NAS, that is all I need, but unfortunately 2011 doesn't have onboard video. Perhaps I can scrounge around for an old video card so I don't have to buy one? Or any other ideas? It's only 30 bucks, so who cares, but it's a waste of money since I don't need a video card except to see the bios.
The power supply is overkill, but I can defend that, too. I need about 400 watts for this, but I also need a boatload of SATA connections. Only 750 and better PSUs have this feature, so I needed to move up to 750. 850 and 750 are the same price, and the 850 will be less stressed comparatively (so it'll be quieter), so I saw no reason to not get it.
The final piece is the one I understand least- the Intel network adapter. I have no idea if it is any good or not. I read in a guide that Realtek (so onboard, I believe) ethernet is pretty bad, and a NAS system will very quickly saturate the ports (partially because of how the CPU treats the port?? Again, I have no idea). They recommended specifically an Intel branded ethernet card, so I threw one on. Any advice on this would be appreciated.
So what do you think? Any suggestions?
At the same time, any suggestions for a prebuilt machine (drobo?) or a different NAS other than freeNAS? I would be very appreciative of the help.
