Ask yourself one question. Is it worth it.
The Hue2 is great, it'll hook up to a serious amount of lighting, with decent software control. But just the box with 4 strips is $70. That doesn't include the extras. Like the fans and ram covers. Fans are @ $30 each for decent fans. You could easily spend $300 just on rgb.
Or get a new case like the NZXT H500i, that has most of that already included, uses the same software. 2 strips, 2 fans and built in case controller. For $120.
As to whether any particular off-brand/generic rgb will work with anything is unknown. That's up to the generics themselves, but if they don't specify they work with mystic light, grid, hue+, Auros etc then it's a good chance they won't. They will work independently, but not as part of the 'ecosystem'.
Those ram covers specify :
- Compatible with ASUS Aura Sync, MSI Mystic Light Sync, ASROCK AURA RGB
That doesn't include Hue, Hue+, Grid or even Gigabyte RGB Fusion.
