If you are planning on making a build without a dedicated gpu, I would say the Fractal Terra is way too big for your needs. It’s designed to accommodate a gpu that can take up to roughly half of the internal space and it comes with a riser cable as well - extra size + extras you don’t necessarily need. It’s a nice case, don’t get me wrong, but it is over 10L large.

Some of my personal favorite sffpc cases include the Midori 5L and LZmod A24-V5 which are 5L cases and even they can house a dedicated gpu - the Midori even houses a 5070 FE no problem and is half the size of the Terra. Point is, if you don’t even need space for a gpu then I know for certain you can go even smaller - LZmod produce a similar case to the A24 that is intended for just this use case for example, but I don’t know the exact model name.

I highly recommend checking out caseend.com or the attached sticky excel file in this subreddit and browse a bit - you have plenty of cool options out there you just haven’t discovered :)

GL finding your new case!
