In Win products aren’t widely sold here in the US. They only have three distributors, Newegg being reasonably priced but only carrying the MS04 SATA backplane version. Speaking of MS04, In Win mentioned to me that they have a new version with a 12G backplane that isn’t widely advertised yet. I forgot to ask: What HSF are you using for your MS08? It’s a slimmer chassis so I’m not sure if a Noctua NH-U12S fits. A 65mm HSF looks like it’ll fit fine but of course, a beefier cooler is nice for a Ryzen build to hit those sweet PBO clocks.
