I have done quite a bit of searching but can’t find a good answer that
suits.

I’m about to get fibre to the house - 900Mbps up and down, so I’m
looking at self hosting some utilities and having a bit of a home lab
setup too.

Currently have a synology nas and use tailscale for remote access to
files. Infuse for media both inside and outside the house. I have
hoobs running on a pi and Pihole on another pi. Network is UniFi - USG
+ 24 port PoE switch.

All is in a rack, but it’s not full depth, something like 430mm. There
is a few U spare, but more like 6 or 7 not 12etc.

Happy with secondhand, happy with rack mount or put on a shelf.
Initial setup would be Linux OS, or potentially proxmox or unRAID. I’d
first just be getting pihole, hoobs/alternative, and d couple of bits
and pieces, but then start to build to include pfsense so I can
replace the UniFi USG, and the replace the Synology NAS when need be.
Also consider nginx as reverse proxy compared to tailscale.
Potentially host photos etc and have something like minim server for
music.

Interested in the most suitable hardware to get me started and be
powerful enough to be able to grow.

I’m in the UK.

Raspberry Pis, especially the upcoming rPi 5 (you can't get one until
next year unless you have it on order, though) can handle  quite a lot
of work if connected to decent storage - USB-connected SSD.

You could also consider an Intel NUC or equivalent. They're low power
and quite capable if given plenty of memory and, again, a decent disc.

For rackmount, smaller Supermicro rack servers turn up on eBay and
they might do you too. The sort of unit that has two disc  bays and a
low power CPU and one PSU is what I'm thinking of.

Bear in mind that lower-end SSD like the Crucial MX500 can be had for
less than £100 for 2TB, so you can get pretty reasonable amounts of
storage for reasonable money these days.

It's worth mentioning Zen2/Zen3 AMD CPUs can now be run in Linux with
kernel parameter: amd_pstate=active
This allows for the CPU to run in an extreme low-power state and scale
up if needed.

Here is the output of cpupower frequency-info.
    analyzing CPU 0:
      driver: amd-pstate-epp
      CPUs which run at the same hardware frequency: 0
      CPUs which need to have their frequency coordinated by software:
0
      maximum transition latency:  Cannot determine or is not
supported.
      hardware limits: 550 MHz - 4.56 GHz
      available cpufreq governors: performance powersave
      current policy: frequency should be within 550 MHz and 4.56 GHz.
                      The governor "powersave" may decide which speed
to use
                      within this range.
      current CPU frequency: Unable to call hardware
      current CPU frequency: 3.59 GHz (asserted by call to kernel)
      boost state support:
        Supported: yes
        Active: yes
        Boost States: 0
        Total States: 3
        Pstate-P0:  3900MHz
        Pstate-P1:  2800MHz
        Pstate-P2:  2200MHz

A refurbished SFF from ebay cheap low electricity consumption and
still powerful
