As the title says, I'm totally new to Unraid but SUPER excited from what all I've seen on what you can do. I want media storage/server with parity-easy---but also want to run Linux,Apple, and Windows VMs and will be gaming with Windows. I've been looking through builds and have this to start. Any feedback is greatly appreciated. Old case I have laying around-should be fine.NZXT https://www.amazon.com/gp/product/B00752QYLU/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Mobo-Supermicro https://www.newegg.com/Product/Product.aspx?Item=N82E16813182995&ignorebbr=1 EVGA 650w PSU--Will I need more considering use of discreet GPU??? https://www.newegg.com/Product/Product.aspx?Item=N82E16817438094&ignorebbr=1 Ram-32 gig https://www.newegg.com/Product/Product.aspx?Item=N82E16820242165&ignorebbr=1 Xeon CPU https://www.newegg.com/Product/Product.aspx?Item=N82E16819117613&ignorebbr=1 Cache Samsung EVO 256g M.2---Will this be big enough, or do I need the 500 gig? And do I need 2 for parity of the cache? https://www.newegg.com/Product/Product.aspx?item=N82E16820147593 Going to use an Icy Dock for 5 of the drives. Two 6 TB hitachi and three 4TB. --This is to start. If I understand correctly, I'll need to also use a discreet GPU--I'll go with Nivida. Haven't picked one out yet. And it looks like my Mobo doesn't have sound-so I'll need a sound card as well? Any feedback is greatly appreciated Edit- I couldn't find my exact Mobo, but found one similar to make a build list https://pcpartpicker.com/list/z8rHtJ
