Need Advice on HTPC Build

I used to build systems but it’s been about 8 years since my last build & I need some advice on parts. Currently, I have all of my DVD’s, CD’s & business files on two MYBOOK World Ed. harddrives & would like to get away from these, and go to an internal raid array. Would love to put a Blueray drive in this baby.

APPROXIMATE PURCHASE DATE: Dec-Jan BUDGET RANGE: $1,000 not etched in stone

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Movie viewing, network file storage, DVR & TV viewing(Sat-tv) light gaming(future).

PARTS NOT REQUIRED:
keyboard, mouse, monitor, Speakers - currently picking up audio thru hdmi cable at TV & rerouting thru analog aux into home theater receiver

PREFERRED WEBSITE(S) FOR PARTS: open
COUNTRY OF ORIGIN: US

PARTS PREFERENCES:
MOBO – 10/100/1000Mbps, SATA 3Gb/s – 6 to 8, SATA RAID - 0/1/5/10/JBOD
HDD – 2 HDDs(1- 1.5tb ea)
Optical Drive – DVD burner & would like the ability to go to Blueray if $ permit
GPU - currently running my pc monitor (1920x1200) & my HDTV(1080p) at the same time thru video card & would like to keep this arrangement with a new card.
PSU – I have no idea what wattage I will need for my complete plan with 8 HDD’s
Full tower case
OS – Windows 7

OVERCLOCKING: no SLI OR CROSSFIRE: no

ADDITIONAL COMMENTS: My current Media Center PC coughs, spits & sputters & ticks me off. Is $1000 unrealistic for this new system? I am planning on future expansion on the HDD’s to 3-8 more, so this will be a work in progress. (beyond $1000 budget)
