The Visual Arts department at my school just got brand-new Intel iMacs for the computer labs, so they're selling the old 700 Mhz eMacs for $75 a pop. I'm definitely planning on buying one, as that's a FANTASTIC deal for a decent machine. I'm planning on getting various upgrads for it, but a friend just told me he doesn't think they can be upgraded. Is that true? I'm getting it either way, but I'm just curious.
