Or pay a small amount more and use an odroid N2 (6 arm cores, 4 G ram)
and run the services via LXC.  I have a dav server, an asterisk PABX,
internet facing web server, slave dns, email and a radicale calendar
server plus a buildhost all in lxc on a single N2.  Everything including
asterisk runs well on a gentoo-sources kernel and a re-purposed Gentoo
aarch64 raspberry pi user-land from my old pi 3B.  An Odroid c4 will
also work - note both of these have USB3 if you want to run extra usb
network adaptors.  The n2 is running a bridge for LXC to the VLAN
segmented networks while the C4 I have (odroid 4.14 kernel, gentoo
aarch64 userland) is using 2 bridged USB 3 WiFi adaptors to vlans all
without problems.  A major performance boost (at least 3x over an SD
card in my tests) is had using the odroid eMMC storage, though the pi's
have a sata hat available - I have tried using usb storage and usb
networking together on both pies and odroids and its a serious no-no :)
- corruption and really bad performance when busy).  The standard odroid
OS is ubuntu and it can apparently also use raspian.

Any pi less than a 4 will suffer from poor network performance (it all
goes through an internal, under-powered USB2 hub), though I have used pi
1B's for all the above services in the past.  Going on my experience, a
pi less than a 4 will do ok for a not very busy home server but wont do
well for routing and a pi 4 should be better at networking whereas the
more powerful odroid units will do it better, perhaps to small
enterprise level with the right storage.  see

have uses a pi3 for the comparison, the newer N2+ is here
