For Chroma! What brands do you recommend?

Alright, with the new Tomahawk cases I can finally put together an ITX build that is fully chroma compatible. My last build looks great, but doesn't work at all with Chroma (thanks Corsair :stuck_out_tongue_winking_eye_:). This thread is to gather recommendations for what works well together and with my Razer gear, as well as get good expectations on HOW it will work together. For example, will I have fine control over internals like I do my Razer brand accessories or will all my internal RGB just be a big blob of color? Here's what I've got so far:

Decided (unless someone has a really good point as to why not):
Case - Razer Tomahawk ITX
MoBo - MSI Z490I Unify
CPU - Intel 10700k
GPU - MSI RTX 3080 Gaming X Trio
SSD - Samsung 970 Evo + Intel (already own these two)

The GPU is technically 3mm too long. Personally I think we can make it work, but if not I may have to downgrade to the Ventus line.

Undecided:
PSU - Only ever looked for ATX form factor so SFX is new to me. Currently leaning towards the Silverstone SX800-LTI. Experience from others here would be appreciated on this. I wouldn't mind some compatible RGB here but I'm pretty sure that's an ATX thing, and I'd rather have dependable quality more than a flashy PSU.

CPU cooler - MSI has a 280 AIO that I'm considering IF the fans and cooler lights work well with Synapse/Chroma. Otherwise I'm looking at Silverstone's IceGem 280.

RAM - I just want it to work with Chroma, is that too much to ask? Previous build was using Corsair Vengeance RGB which has a ton of nice effects, but even the MSI/Corsair software was hit and miss as to who would control the RAM. Currently I'm looking at GSkill Trident, either the Neo to match the MSI cooler or Royal to match the Silverstone cooler.

Case fans - Not a clue. If I go Silverstone I could just get some matching fans, MSI doesn't have that option but I'm open to something else that would work well with the motherboard and Chroma. Thoughts?
