I stand corrected. It's two times cheaper for new ones.

Sorry, this usage grates with me.

$amount cheaper that $price means subtract $amount from $price

$x times $price means multiply $price by $x

so "2 times cheaper (than $450)" is:

$450 - (2 x $450) = -$450.

so what multiplied  by 2 gives 450? 

450     is      100% or 1
225     is      50%  or 1/2

perhaps this is the confusion, cause we are using daily language to refer to
maths. 

In fact I would do it the other way around.

initial price   x
1xtime          x+(1*x)
2xtimes         x+(2*x)

this gives x=150

The problem is in the comparison - when you read the characteristics of the
devices, there are couple of differences that can not be neglected, but I
agree 400 is too much. I think fair price for such a device would be in
200-300 range, what we also see for the Lynksis router.

Right, so 225 is 50% cheaper, or half cheaper. Not twice cheaper.

Daily language is the problem, yes. I'm not saying my fight is an easy
one :-)

450 is two times more expensive than 150 (or 200% more than), or three
times as expensive as 150 (or 300% as expensive).
300 is two times as expensive as 150, or 100% more expensive than 150

We know that these don't work symmetrically; if you have a 50% discount,
you can't get the original price back by adding 50%, because it's 50% of
a different number.

"Expensive" is a dimensional term, like length and time. "Cheap" is in
a different category, like shortness. A 6-inch nail is twice as long
as a 3-inch nail, but one doesn't say the latter is twice as short.

But if someone asked for a nail twice as short as this (holding up a
6-inch nail), you might assume they were a non-native speaker of
English, or you might notice you're almost twice as tall as they are:
ie it's a child. (And it would be polite to offer them a 3-inch
nail. Learning all the categories takes time, and some people might
have slightly different boundaries.)

It's pretty obvious that Reco's meaning for cheapness was meant to be
understood as a reciprocal cost and not as a discount. It might be a
legitimate idiom in some parts; who knows.

One hears stories of pedants insisting they be paid to carry goods out
of the shop because they were labelled "10x cheaper". No way José.

Cheers,

Agreed. I prefer to avoid multipliers with inverted dimension terms like
that.

I wouldn't assume that; it's a common usage, even though I consider it
wrong :-)  A bit like the American habit of saying "I could care less",
which also doesn't mean what they mean it to mean :-)

Agreed. And many would consider it a 'legitimate idiom'. I personally
consider that from a linguistic and mathematical perspective, it doesn't
make sense.

I haven't actually insisted on that, but I've certainly thought it :-)

Similarly, one of our local fuel stations has (or had) vouchers that say
things like '10c per litre off every litre of fuel' - which also quickly
gets into trouble if taken literally :-)

You mean that would mean 20c off the second litre and 30c off the third,
and so on, or something else?

I really don't know. It seems 'every litre of fuel' is where the phrase
goes wrong and that part could profitably be deleted, leaving simply:
'10c per litre off.'

Anyway, whoever wrote that must've been gassed (so to speak).

They are currently at fourth "campaign", i.e. they're manufacturing a
fourth batch. Supply is limited (they produce like a thousand boards per
batch), your best bet is a preorder (I got mine at their second
"campaign").

Hopefully they do fifth.

Have you considered OpenBSD?  Security is their top priority.

Have you considered a mail hosting provider?  The Internet is a war zone 
and mail servers are prime targets.  Are you prepared to fight that 
battle 24x7?  Do you want you home IP that visible?  Will your mail 
users tolerate down-time?  I provide e-mail addresses for myself and for 
family members; I pay professionals to host my mail service.


Hosting Nextcloud locally allows you to get at your data at LAN speeds, but:

1.  Do you have a good firewall/ router, and know how to use it?

2.  Will Nextcloud run in a DMZ?

3.  Does Nextcloud require a public IP -- e.g. DNS or dynamic DNS?

I prefer Intel brand motherboards, and Dell products with Intel chips, 
because the hardware quality is good, support documents are available 
for many years,  and Intel supports FOSS with reference source code. So, 
a given FOSS OS distribution has the best chance of working OOTB on such 
hardware without needing binary firmware.  That said, the Intel WiFi 
board I installed in this Dell laptop does require binary firmware.

More than one can be very useful.


> A USB3.0 port or SATA connector to attach storage to.

Internal headers, internal ports, or external ports?


SATA DOM?


M.2, etc.?


I have had issues with FOSS and USB 3.0 ports.  USB 2.0 is slower, but 
more reliable.


I have found internal to be more reliable than external.


Get at least four internal SATA 6 Gbps ports -- boot disk, optical disk, 
two data disks (mirrored).  I prefer six.

Get a processor with AES-NI support.


Get a motherboard that uses ECC RAM and get ECC RAM.  Research your OS, 
file system(s), services, etc., for the amount of RAM needed, and pad 
according to budget and market price points.  I would not get less than 
2 @ 4 GB ECC.

Do not connect an Ethernet port with a management chip directly to the 
Internet and/or disable the management chip in the CMOS setup.  If the 
box has more than one Ethernet port and you want the management 
features, connect the Ethernet port with the management chip to a 
air-walled administration LAN.

I have many doubts about SBC's and SFF computers -- fewer memory, 
expansion, and I/O slots and ports; fewer choices for processors, memory 
modules, cases, power supplies, expansion cards, etc.; fewer drive bays; 
heat issues; long-term vendor support; and the total system cost is 
always higher than an equivalent tower desktop or server.


I built my computers from good quality, standards-compliant, COTS 
desktop parts for 20+ years.  This allowed me to mix-and-match as 
required when parts died or became obsolete.  I still have two 64-bit 
desktop machines in use, and two 32-bit machines packed in their 
original boxes in the garage.


Then Intel stopped making desktop boards and I wanted ZFS.  ZFS wants 
ECC memory.  It was time to migrate to server hardware.


I needed to upgrade or replace my SOHO server late last year.  My old 
SOHO server was based on an Antec full tower ATX case and had an Intel 
D945GNT motherboard, Pentium D processor, and 2 @ 1 GB RAM.  One memory 
slot was bad, preventing installation of 4 @ 1 GB RAM, and dm-crypt 
without AES-NI cut disk performance in half or more.  I replaced the 
motherboard, CPU, and memory with a used server parts:

https://www.ebay.com/itm/Intel-S1200V3RP-Server-Board-Xeon-E3-1225v3-SR1KX-3-20GHz-8GB-Ram-I-O-Shield/123431007451?epid=1941949226&hash=item1cbd0fb4db:g:UuIAAOSwNJlb~bQi:rk:10:pf:0&LH_BIN=1


It works and the performance is amazing, but the case is bulky, the 
total system requires a fair amount of power, the fans are noisier than 
I like, and the internal 3.5" drive bays lack vibration isolation (so 
the HDD heads clatter).  Furthermore, I was using old HDD's and several 
died in as many months.  I needed something more modern and reliable.


I thought about putting a new Intel single processor server motherboard, 
Xeon processor, and ECC memory into my Antec Sonata III 500 case, but 
the cost was prohibitive ($600+).


I ended up buying a gently used Dell PowerEdge T30 for US$375.  It came 
with a Xeon E3-1225v5, 1 @ 8 GB ECC, 1 TB SATA HDD, and CD/DVD+-RW.  I 
removed the HDD and added a PC expansion slot 2.5" drive rack, 16 GB 
SATA SSD, 8 GB ECC, and two 3 TB enterprise SATA HDD's.  Total price was 
less than US$700.  It runs FreeBSD 11.2, GELI, ZFS, jails, Samba, and 
CVS.  It is energy efficient, quiet, and very fast.  The only downside 
is that the internal 3.5" drive bays lack vibration isolation.  (I need 
to add sheet rubber to damp the vibrations.)  This was the best value 
proposition I could find.  I hope to run it 24x7 for many years.

Excellent advice.  A single Newsguy account will provide all the
addresses you need.  You can have your domain registrar redirect mail to
your Newsguy account so you can still use your domain name.  Since you
would be paying them (about $5/month) you would have an actual contract,
unlike "free" services such as Gmail.

Do most people running servers really want / need an optical disk? As
long as the machine can boot via USB, is an optical disk really
important for a server?

My understanding is that ZFS's need / desire for ECC is something of a
myth. It's certainly true that many ZFS / FreeNAS *users* have such a
need, but the filesystem itself apparently doesn't:

To summarize: if you're running ZFS, it can protect you from
lots of sources of data corruption. It can't protect you from
RAM errors without ECC, so you should opt for ECC if integrity
is your goal.

None of the other filesystems protect you against RAM errors
either, so this is not a special requirement of ZFS.

ECC memory is rare among ARM SBCs, but Helios4 uses ECC memory!

... with the only problem being the quantity of such RAM.

A typical Helios4 board has whopping 2Gb of RAM, which is about 4 times
lower than needed for comfortable ZFS usage (assuming that zpool size is
measured in terabytes) and a user intends to run something more than a
OS kernel and sshd.
That estimation deliberately excludes all advanced ZFS features (such as
compression, encryption and deduplication).

IMO for such RAM sizes it's better to use old trusted MDRAID, LVM, ext4
and a new kid on the block - dm-integrity (all the needed tools are in
buster, but some assembly is required).

For the record I did not recommend using ZFS on low-end hardware.

The OP asked for advice in buying low-end ARM-based hardware for use as 
server, and I pointed out that one ARM SBC (likely the only relatively 
cheap one) is known to use ECC memory - which (as the previous poster 
pointed out) is interesting _independently_ of choice of filesystem.

Personally I use ext4 with journaling enabled, on either conventional 
rotating disks, SSDs, or sdcards (no RAID involved).

So is the general consensus that there are no modern SBCs powerful enough to run nextcloud on (apache, mariadb, php) or a mail server (typical postfix, dovecot, opendkim, SpamAssassin etc... ) for a handful of people? That seems hard to believe.
