How to heat up that room that is always freezing

Optane makes sense if your machine don't use SSD but your workload needs to do a lot of disk access. If your workload needs a lot of RAM, then Optane will be much slower compared to adding real RAM. AFAICS, Optane is meant to fill a gap for budget systems that don't use SSD but requires the performance of SSD. I'd suggest that if you're going to reinstall a new system on a new hard-disk but thinks that going full SSD is too expensive for your storage requirement, you might as well get a Hybrid SSD+HD, it's simpler and have much of the same benefits.
