My employer runs more than a hundred Debian servers, mostly on
Supermicro hardware, but some HP as well.
We have very few hardware problems.

We are firmly of the opinion that mdadm or ZFS are the best
solutions here.
To give an idea of what you might buy:
a firewall/router
a switch
a load-balancer
2 web servers
a database server
a mail server
a general utility box with lots of storage to handle backups
All of those duties except the switch can reasonable be run on
Debian servers.
a firewall/router - nftables. You will want at least 3 ethernet
ports. CPU is not usually an issue. RAM is never an issue.
Disk space can be tiny.
a load-balancer - ldirectord, or haproxy, or possibly nginx. You
won't need much CPU unless you run SSL on nginx. You won't
need very much RAM, or disk space.
2 web servers - nginx or apache or whatever makes your
developers happy. These probably need CPU and a fair amount of
RAM, but not much disk space
a database server - postgresql. This will be your biggest box,
with large disk arrays and lots of RAM and fast CPUs.
a mail server - postfix. This might need lots of disk, depending
on what you're doing, but even a terabyte is actually a
ridiculous amount of mail storage for a small company.
a general utility box with lots of storage to handle backups -
on which you might run your DNS server, NTP server, store
logs, and run borg or rsync backups of the other machines.
You might consider a git server, too.
