For current ElectrumX version:

ElectrumX is actually pretty lightweight CPU wise. It will run fine with an old Xeon.
RAM use is 340 MiB not counting buffers. More is always better up to a point.
Network bandwidth is not bad for a public server, easily serviced with a home ISP connection.
Total storage is small - 49 GiB total ATM.
The resource constraint for a public server is really the storage I/O. ElectrumX needs to index each block as it comes in and does some thrashing for a bit each time this happens. SSDs are definitely recommended.

You of course have to have a fully synced and txindexed bitcoin core node already running. And you won't make any $.

The real benefit to running your own server is privacy - you can use Electrum with just your server and node.

Thanks for the insight, but could you tell :
1. How many cores of Xeon you use? 2? 4?
2. Since you mention Xeon, do you use shared VPS (which could greatly affect I/O storage performance) ?
3. 49 GiB excluding blockchain/indexing file from Bitcoin Core?
