If you buy the standard noctua fans, they come with official Y-splitter so nothing janky about them or any other Y-splitters as well. Most headers supply 1A or even 2A currents so plenty enough to power several fans with multiple Y-splitters.
Should be ZZAW B2. They also have B1 which is more standard looking. To be honest I think the B2 looks ugly haha.
Thanks, and yeah the first two is more of a M1 layout, theres not much like the Papyrus as its a unique layout. Sorry that I am unsure of the interstellar as its quite new. Hopefully the seller can reply you.
Its quite an unusual layout but I found a few cases a bit similar.
BTW, the seller have updated this case to version 3 below and the original one is discontinued. GPU length increased to 244mm and CPU cooler height increased to 58mm
They are all should be genuine Enhance PSUs. I did buy one from the taobao store. Enhance does not sell PSUs directly to consumers so all the ones I listed are all resellers. There is no so called "original seller"
Recommend the Enhance ENP-7660B 600W Platinum as it has a quiet fan. It is available to purchase below
Cant really find a case with those requirements, especially front intake fans and 160mm cooler height. Some cases I can find that support some a part of your requirements are Sunmilo C01, SKTC Q1/Q2/Q3, POLARCASE SC, Deng F15 Pro, Mechanic Master C34.
You already got your case delivered to the warehouse? It should be much faster as they just need to ship it. Mine was told to be end of March as they havent even start making my case lol. Hopefully everything can resolved soon enough.
