If you are short on hardware or money, one option is to install Debian 
onto a USB flash drive.   I ran desktop hardware as servers on USB flash 
drives for many years, and still keep a Debian 9 system on USB flash for 
maintenance purposes.  I have yet to wear one out.  If you feel the need 
for RAID, use two USB flash drives.
