...do you think these specs would be about right? I based them on the Lindbergh platform but scaled them back as Sega did with the Dreamcast from the Naomi's hardware (i.e. half the main/GPU RAM)

CPU: Mobile Pentium 4 HT @ 2.4GHz (maybe 2.0Ghz)
RAM: 384Mb DDRI (or maybe 512Mb DDRII 533Mhz)
GPU: GeForce Go 6600 with 128Mb dedicated
OS: Probably some customised Linux variant.
HDD: 20Gb HDD (maybe replaceable as the Lindbergh and this system is basically using off the shelf PC parts).

I think this would probably be able to handle slightly/somewhat scaled down Lindbergh ports pretty well. I'd imagine Virtua Fighter 5 would have been pretty close to the PS3/Xbox 360 versions too.

Thoughts?
