I didn't know a default unmodified N900's case has a place for these This is a project for upgrading the hardware core, which accidentally needs also motherboard replacement. The things you said are rather peripherals. About storage flash - GTA04 has only 1GB of storage (afaik)... but again, N900 has only 256MB of rootfs, so this would be a stunning 4x upgrade! But the eMMC is included as a separate chip (meaning we have like... two memory cards inside allready, but one is unremovable). By the way, would GTA04 be capable of supporting that kind of config (eMMC + external memory card slot anyway)? Well, screw that anyway, I guess it's far to early to ask that kind of questions, just wanted to bring attention to this point
