Hello!
I could use a recommendation on a few things related to building an HTPC. if you have information on *any* of the following it will really help.

OVERVIEW: I'm trying to build an htpc, that's really a full pc with htpc capability, that looks like an htpc (for fun!). Mostly I'm trying to put together a full pc with 2 optical drives, and hopefully a bunch of room for internal drives. I almost want a full pc in a home theater style enclosure. it would also be great to lay the groundwork for pro-audio in the future. here's some of the features I'm looking for

-output to optima HD72 projector (720p resolution, DVI or hdmi input)
-capture and playback of TV from time warner cable
(motorola 6412 dvr with firewire output)
http://broadband.motorola.com/dvr/dct6412.asp
-windows x64 os
-possible dual boot with Windows MCE, or XP 32bit

-*** potential use for music production?
I would love to try and get components that I could use for music production
as well, if it's not too tall an order

************************************************** ***********
I could use *recommendations* on all these components from experienced users:

1- Case
Anything that looks htpc, with full pc on inside like the thermaltake BACH series or silverstone lc20

2- mobo/cpu
thinking amd socket AM2, but still doing research on mobo's
I'd like to consider
-performance for 3D, professsional and gaming
-HD playback, 1080p if possible (hd audio?)
-performance balanced with heat dissapation for silence.
performance is more important, but I'll pay a little more for something
which will work better with silence
-possible attention to video/music production as well

3- graphics cards
Do I need something with hdcp if I want to get hd-dvd or blu-ray in the future?
hdmi output needed? or just dvi? *sigh*

4- sound card
no research yet. DTS output would be nice. Analog input for music would be nice, but I don't think I can afford a $900 sound card yet (but it would be nice to have a system I could put one into if I wanted to add pro sound later)

5-capture/cable cards
to my knowledge, there are no cards which tune digital cable yet? is there any card taht will offer me functionality over just connecting to the motorola 6412 with firewire?

6- um... anything else you'd recommend

THANK YOU SO MUCH FOR ANY ADVICE!!!
