I haven't looked into multiple displays, so it is something to consider. But really, in the home theater environment, there's a big ass screen, and a couch some distance away (and a dizzying array of speakers), so where to mount the secondary display(s) becomes an issue. Furthermore, when you have a 13' diagonal screen right in front of you, are you really going to want to play on another screen (even a sweet 30" Dell)? Now, in the home office, multiple screens sounds much much more appealing (unless there ever comes a method my which one could put panel displays from SFC onto a small screen while the big screen shows the main display (drool)).
Regarding the specs for the JVC projector, it only has 2 HDMI inputs, but one of those inputs are through the Onkyo AV Receiver, which, in itself passes on the video signals from, I don't know, 9 HDMI inputs. The point is, there are HDMI inputs to spare from my AV Receiver to the projector. The projector handles 1080p beautifully, so it should be able to handle whatever a video card puts out (JVC DLA-RS25), with resolution of 1920x1080 (

Normally I don't like futzing with batteries either, but given the layout of the theater, I don't think I have a choice in this case, wherein the components do not have line of sight. And given the size of the room and seating, they're far away. So I think I need something that can withstand even a little drywall between the keyboard/mouse and the CPU, so I'm hoping bluetooth will do it for me (confirm?).
Sorry if I am delayed in responding to these posts. I'm now working away from home. And I currently understand that in order to be able to afford such cool toys, one has to have a job apparently that precludes one having enough time to actually play with said toys.
Could be worse. If I ever get this up and running, will send pix.
Thinking that I want to make the effort towards a kickass rig with dual boot. I'm turning into an old fart, and
I am sure there will be other legacy games that I will want to access so the XP becomes worth it. Right now I've got to decide whether the performance hit I will take in insisting upon a laptopish (albeit desktop replacement size) solution versus just getting a regular non transportable box. I'm beginning to think that it may be not worth it to make the CPU transportable, given its a pain in the ass to get to the components in my home theater in the first place. And I have an old laptop, but it does what I need.
