There are suppliers who will construct a machine based on the components you
select, and who will also help you in making the choices, if necessary. I
would expect similar vendors to be available in your country/region.

I have an HP workstation with a serial port. The newer models also have them.
Mine is also certified to run Linux (Red Hat, specifically), so when I
acquired it at an online auction I knew it was very likely to be well
supported, even though I was running Debian rather than Red Hat. The hardware
was about a year old at that point, having been used by a distributor as a
demonstration machine.

It also came with high-performance features such as 15 KRPM SAS hard drives.

Yes, or get a workstation-class machine rather than a regular PC, and buy it
slightly used to bring the price within your budget as I did. They usually
have ECC RAM, high-performance CPUs, good fans and power supplies, etc. Of
course, you could just buy the components and have a comparable system built
for you.
