Something I’ve been looking for on the Orthanc website but can’t seem to find is a core server spec, CPU cores and RAM etc. I don’t want to under power my first install.

Simon
Orthanc is lightweight and will run on any computer that is able to run GNU/Linux. For instance, it will smoothly work on a Raspberry Pi as well as on a micro instances of virtual machines by cloud providers.
One CPU core is enough to run Orthanc. Obviously, you should scale as soon as you need performance or to handle multiple users, but this really depends on your very specific scenario.
As a rule of thumb, RAM should be at least 4 times larger than the largest DICOM instance you’ll have to handle.
Disk space directly depends on the amount of DICOM instances you’ll have to store (add a security margin of, say, 50%). Configuration option “StorageCompression” can be used to reduce the storage area by compressing DICOM files (which evidently requires more CPU power).
This is for cheap, entry-level deployments. If you want to scale, check out the following page in the Orthanc Book:

Excellent, thanks. I suspected as much but just wanted to make sure.
best regards,
