Both HDD and SSD are IMO too small.
For HDD, the 1TB is inefficient: €51 for 1TB, €98 for 3TB — that is more than 50% difference in cost/TB (both for WD blue desktop series as listed on computeruniverse.net).
For the SSD, the 256 GB is just too small. Sure that’s enough to boot Windows, but not enough to fit more than a couple of modern games, they easily take 50GB/each. I’d rather recommend 480GB these days.
