The only reliable way is to do some testing. Now 10,000 rows a day isn't
many and I doubt it will be 10-15 simultaneous writes (although it might
be 10-15 simultaneous connections).

The key questions will be how much of that 20GB gets used regularly, and
what level of performance you'll need.

The best way of finding out is to do some testing - use a standard
desktop machine (or laptop) and see how that performs. Make sure you
have a realistic mix and amount of data though.

If I had to guess, I'd buy a cheap server with some SATA disks (at least
2 so you can mirror them) and as much RAM as was left in my budget.
