The only trouble with on-board video is that it's often impossible to get a multi-monitor setup.
It all depends on the monitors used
I have a pretty nice 25.5" 16:10 monitor with HDMI, DVI, VGA, and even component inputs. I love it and would like another but sadly this model has been discontinued.
My secondary monitor is a 19" no-name brand (DCLCD) with only a single VGA input. Not that great, but I got it nearly 10 years ago and it still works. I wish I could say the same about the more expensive 19" ViewSonic LCD monitor I bought about 6 years ago.
Either way, if the onboard video doesn't support multiple monitors, then I can make due with just my nice one for a while or plug in my GeForce 8600 GTS and use that in the meantime.
I do intend on getting a discrete GPU eventually, but it was really stretching my budget to get one now. So maybe by Christmas I can save up for (most of) the other parts I wanted.
On another note, good choice with the case - I've been looking at getting the Scout for a while. My friend has one, the LEDs are quite subdued and can all be turned off via one switch on the top panel.
The only bad thing I'd have to say about it is that the carry handle is not designed for human hands - its cross-section is equivalent to a piece steel rectangular tube and the corners dig into your hand. You'll find it a lot more comfortable to wrap a bit a high-density foam, (1/8" thick), around it as I did with my friends. But if you don't envision carrying it around, or only infrequently, then no problem.
I was a little worried about the case and how noisy it is. Can you tell me if it was especially noisy or quiet? Or was it just average? I guess that may depend on what other parts your friend has inside, but I'd still like to know.
Keep us posted and maybe put up a picture or two?
