I'd say the risk (and costs for defects) is higher than the price for service. Main risks when upgrading CPU and graphic card: electronic defects by overvoltage (sorry, don't no the exact english expression just now), overheating of new CPU and cube at all. It's a tricky thing!!! And finally the risk of an overcharged DC/Board is surely the main problem. A faster CPU can bring problems and before all a new, faster graphic card. Powerlogix offered a stronger DC/Board. Is it still available? I regret to give an unpopular advice (am I a Cube-renegade ????) : Buy an Intel Mac mini (the fastest if possible). That's surely no designer's tip and of course no idea a mac vintage enthusiast would ever give you. But it's a device grown of rationality. A Mac mini Intel Duo Core is faster (out of the box!) than a Cube can ever become. Rendering a videofile will be 4-8 times faster than my 1.5 GHz Cube can do it! (Study the performance comparison!) It is very silent, economic in power consumption, has built-in USB 2.0, Airport extreme, bluetooth. What else can you want...? You can speed it up if you combine it with a 3,5 S-ATA drive (means you can have a new 500 GB+ drive). See the interesting advice/review at AMUG. If you buy it secondhand but still with guarantee of apple it will cost you probably 600 Euros (500$ ?) A similar amount you will have to spend for upgrading your cube. (If you sell the cube for about 200-250$ it might be even less expensive for you) I like my Cube, speeded up with a Powerlogix 1.5 GHz CPU (with 1 MB Cache!, the fast one), 1.5 GB RAM, a GeForce 4 MX and a DVI-TFT. But this Mac becomes old and one day it will die - surely. All that is no simple decision, I know. Wish you a good one. Regards Stefan
