<div>Just so you've got some context, I've got the N40L model,
running with 8GB RAM and 4x 2TB drives. 2 of the drives are
running btrfs as root (/), and the other two are /backup.
Everything else is stock, no custom RAID cards, etc.</div>

I'll answer similarly for one of the ones i recently deployed: N40L,
stock 2 GB RAM, 4 x 2 TB drives; first 32 GB of each drive is RAID 1
for boot volumes, remainder of drives is a single RAID 5 partition.<br>

<div>It's got a massive fan at the back, but it's at the
ambient fan noise level you easily ignore. The drives are
louder when they are doing lots of writes. In fact, my
laptop when it's running super hot is louder than it. So I
personally don't notice the noise coming from it.</div>

General consensus is it's very quiet. Because it's a 12cm fan, it
seems much quieter than any tower or rack mount server i've ever
used. (But my hearing might be bad after sitting in the same office
as a ProCurve 3400cl switch for too long. :-)<br>

<div>I can't really comment on this one. I've never noticed
it to be an issue for anything I've used it for, and I did
have it as a VPN end point for my work at one point so it
saw a lot of data throughput without any issues. Also, I
usually have 2 VMs running in Virtual Box on it and all
three machines (host + 2x VMs) seem to be quite responsive
for my needs network-wise.</div>

Here's a graph from ours:

This is running on the inbuilt network card with no attempt to
optimise performance. Usually the bottleneck on our backups (which
is what this traffic is) is either the source or destination disk.
Never the network unless it is plugged into a 100 Mbps port. This
server is plugged into a Gigabit copper port.<br>

None. The server graphed above is actually running CentOS 6, but
the latest one i've deployed is Ubuntu 12.04.<br>

I think it's a pretty good compromise between the two. My next
personal server will be one of them for sure.<br>
