I'd go with Focus G. Few reasons:
1. Better frontal airflow (meshed front panel).
2. Better fan compatibility (can hold 140mm fans at the top).
3. More fan mount locations (has 1x 120mm bottom intake over 100R).
4. Comes with 2x 120mm stock fans (100R has 1x 120mm stock fan).
5. Better CPU cooler clearance (165mm vs 150mm).

The case specks are a bit wrong for the 100R it will fit a hyper 212 CPU cooler.
The Focus G is still a much better case with the dust filters and better fans.
