From what I've gathered it depends on how you sleeve. If you want to do every wire individually then you will need more than one pack. What I plan to do is do the PSU wires in pairs. You will use half as much that way and I think the effect will still be pretty good. Depends on your budget I guess. Seems like a pretty good deal, pretty close to getting free postage if you compare it to buying directly from the states... I think glen is going to receive a pallet load of orders.
