For 16 cameras I would get at least 1Gb of RAM just to be on the same safe.
There's nothing really you can change in the specs that affect the capacity of the PCI bus so you can have the fastest computer in the world but it's still going to be stuck if you have a motherboard with a single PCI bus. As suggested in
this thread it's probably worth checking with LML to see whether they think a twin bus setup would be necessary for 16 cameras.
As for storage, you have to define what you mean by 'high quality footage' to determine what you need. If you're talking 320x240 at 1 frame per second with 70 jpeg quality setting, so each image is about 15k, then you'd be talking about 16 x 7 x 24 x 60 x 60 x 15000 bytes of storage which by my reckoning is 145152000000 or about 145Gb (I think). But if you are thinking 640x480 then quadruple that and likewise if you want 5fps rather than 1 you will have to multiply it by five. Also don't forget that as you write more images to disk you may start to hit disk transfer bottlenecks so might want a RAID disk array to be able to cope.
It's all a bit hit and miss really until you can exactly pin down your precise requirements.
