Re: SSDs, it's still too expensive/GB at the moment, especially if you include a bit of redundancy (at least RAID5-grade). I'm looking at 8-10TB with all my disks (not buying everything yet) - and yes, I do need this kind of storage (I often do some processing on very large datasets).
I'm planning to use software RAID (via ZFS), so hardware RAID matters very little.
Agree with the concerns regarding network bandwidth. I'll be using 1Gbps Ethernet when I'm close to it, but unfortunately my housing is not wired with RJ45 so I have to use 802.11 most of the time. 802.11ac should be around 800Mbps, which I consider "enough" for most uses.
Re: CPU power, I expect writing at ~100MB/s with AES encryption is going to be more expensive than you expect. According to what I see on the internet, this i3-4130t should manage around ~400MB/s at peak. ZFS also has some non-null overhead, and I might consider some encryption/dedup. If you add the load of some random server apps running on it, I think it's not too extravagant. Also, it's a very low TDP CPU for how it performs.
