Home server on a budget advice

[Tirpitz9]

I need some help deciding on a server.
Use:
    Nas (to replace a struggling readynas 204) to finally get a usable network mount to work on live.
    Nextcloud ( ~6 users up to 18 sync clients)
    Database server to handle other applications
    Plex server
    Development environment
    Web scraping (continuously checking websites slowly, 1 request/sec or so)
    DNS sinkhole
    Ha proxy for next cloud and octoprint (running elsewhere on the network)
    This will probably be set up on a container system (docker).
Will a single E5-2420 with 32 gig ram handle this?
Or would a dual x5620 with 32 gig be more suitable?
Which CPU grade/group of CPU should I be looking at?
Do I need to look at spending significantly more?

Hoping to spend less than £200.

Edit: will also be running a steam cache server.

And Plex will only be catering to 2 users and only rarely transcoding if at all.

Will there be a need for Plex to do transcoding of video? If yes, I'd pair that with an NVIDIA GTX1000-series and Plex Pass, so you can take advantage of H/W-transcoding. Otherwise, yes, it'd be able to handle that load easily.

Usually no more than 2 concurrent users, usually no transcoding,
