OK, this is a complicated series of questions, so bear with me. I am soon to inherit a G4 Cube from my dad (he's upgrading to a G5), and am weighing the pros and cons of upgrading the Cube versus buying a Mac Mini. Here is what I plan on doing to each, and the relative cost: Cube: 1.2 Ghz Sonnet Upgrade $310 (on newegg.com) 1.5 GB PC100 RAM (has 512MB now, so 2x512) $130 Have a 200GB 7,200 RPM HD 8x DL DVD-RW drive (from friend) $150 Total $589 Mac Mini 1.42 Ghz 1 GB PC2700 RAM 80 GB 4,200 RPM HD 4x DVD-RW at Education pricing, $969 My questions are as follows. I know that PC100 RAM is significantly slower than PC2700, but would it make that large of a difference in speed? Also, would the extra 512MB of it make up for that difference? I'm also worried about the hard drive. I know the Cube uses ATA-66, whereas the drive is ATA-133. I know they're downwards compatible, but would that big of a speed drop really take away any advantage of using a 7,200 RPM drive over a 4,200? Finally, I've heard about the new Gigadesign dual 1.6Ghz upgrade for the Cube which runs at $749... thought it's more than twice the cost, would it be worth it over a 1.2Ghz Sonnet? There's no big rush on this as I'm not planning on getting the Cube for another two or three months, but I'm curious as to what you all think. Which should I go for?
