If you have the money, go for it but if you want a long life I sugest you really do something about the cooling because allthough the BlizzardPPC has been built for trapdoor design, it is not suited for it.
You have to direct a fan on the processors of the BlizzardPPC and also on the chip of the BVisionPPC.
This will grant you a long life and there is a French company also doing BlizzardPPC repairs these days so you can get it repaired when it dies.
If you are not going to play games then a Mediator with a 060 card is also a good way to go.
