So my old HTPC slash central hub PC is time for an upgrade... its been 8 years since i did a build.

Need a new cpu /mobo combo that will act as an HTPC semi NAS hub for other devices and hopefully a new operation as a controller/storage for two HD IP (hicvision etc)security cameras.

system is in a dedicated full sized case so mobo size isnt important

so specs needed:

Low power as its on 24/7

grunty enough to play and stream netflix via fiber or play 4k movies stored on the pc via kodi( while still recording the 2x cameras?)

MUST have hdmi and optical audio out.

have the latest high speed usb and sata ports

i may possibly consider repurposing my current PC as a dedicated camera controller/storage but as its old its not my preferred option.

might look at throwing plex in there smewhere too to store/stream media and camera feeds?

any advice on what im planning including good free camera software etc would be great

An Intel Pentium or Atom should do just fine. If you want Plex, you want more cores. I run Plex quite happily on a FX-6300 - 6 cores and enough grunt to run 4 simultaneous streams.

All things considered, I'd probably suggest you go with something like a Ryzen 3 2xxxG CPU with some sort of ASRock AB450 board

With any new system you should get lower power consumption than your old one. When I upgraded my MythTV and Windows boxes a couple of years ago, I got much faster CPUs, twice as much RAM and the power consumption when down by about a third. For a 24/7 box, it probably pays to get an 80 Plus Gold or better rated power supply - that means that it will be 87% efficient or better as long as you are drawing in its (wide) mid-range of power output. Cheap power supplies can be only 60% efficient. And do not get too big a power supply - that can mean that you will often be operating it below the mid-range where it works efficiently.
