With what parameters to buy a server for (LAMP) + memcached + sphinx + imagemagic?

Question

Sphinx

Hello! :) Guys there is a service on the local machine, a network for photographers, perhaps someone has seen sites analogous to 1x.com 500px.com... all of them (including the site on the local machine) work with large images in size and quality, the ceiling is .jpeg file 50mb. After uploading the photo, it is processed by imagemagic (local site), compressing from 200kb to 2mb after the script scatters 2 files into folders, now it takes about 1-90 seconds to process one photo, despite the fact that there is no one on the server except me, he only processes one image, so we decided to buy a dedicated server - ru.hetzner.com/hosting/produkte_rootserver/px60ssd I have no experience with high loads, I really want to know the opinion of experts on this matter ...
Will this server be suitable for 2000-5000+ in day online?
Isn't a 240GB SSD too small for such services?
Is 32 GB of RAM enough for such loads (it is supposed to store a lot of data in memcached)
I will be glad to know how you allocated memory and how you chose the Server for highly loaded sites...
Briefly about other resource consumption:
- more than 40 tables in MySQL
- indexing 20 search tables (sphinx)
- a lot of ajax requests
- almost 70% of the photos are expected to be loaded when interacting with the service
- more than 90% of all information about users in memcached

Answer 1

SSD 240GB for hosting source images, it seems to me that it will not be enough.
