Any of the three will work. My personal preference by far is a silent Windows based PC. Doesn't look like a PC if you choose the right enclosure. It can be built for about $1,500 including an audiophile sound card, graphics card and very good Blu-ray optical drive. Due to driver restrictions for the sound card it has to be W7. Sounds phenomenal and no noise what so ever. Allows you to do everything on your list and then some. Personally, I fought this approach for quite a while. I am totally happy that I finally did this.
If interested I can give you the Email address to inquire and obtain the sound card. I can give you some advise on components as well.
Best of luck!
