Here's my setup in my tiny apartment.
2x Polk Monitor 50 tower speakers
Onkyo HT-R160 7.2 Receiver
Old Philips 47" TV that needs a 4k Upgrade
Polk PSW-10 100W sub
And the Media Server is running Win8 Pro and is driving the TV and has PMS Virtualized on a FlexRaid array consisting of a psudo-RAID5 with 6x2TB WD Caviar Blacks driven by 2x250GB OCZ Vertex 3's
With an i7-3770S, 32GB ram, and 3 teamed-gigabit NICs, I can serve 6+ 1080p transcoded streams simultaneously.
PMS serves this stuff up all to these devices
Bottom one being a TV in my bedroom closet.
I can't wait to own my own house so I can make everything all pretty.
