On the other hand, eventually I plan to be running SAC/SAW setup, at that point the extra mound of RAM may be handy dontcha think?
Fair point on your MOTU investment, I can't guarantee that you'll get better performance with RME, I just expect that you will. The RME RayDAT is 4xADAT in 4xADAT out - 32 channels total - it's a PCIe card. I don't know how many PCI/PCIe slots you have in your 1U case, but if it's one, which I guess it is, your only option is MADI, which is expensive.
The speed of your hard disk is not going to influence the performance of SAC. The quad core which is being used elsewhere, whilst having extra horsepower, may not achieve the low latencies you are getting from a dual core due to the threading issues Bob frequently mentions.
I still don't know how much RAM SAC and SAW together need, perhaps Bob can chime in, I think he may be able to give you a figure for 72 tracks of SAC feeding 48 ins on SAW. And of course, if you want to run other things like VSTi's the extra RAM may come in handy. Personally, I suspect it will be a disaster, I'm just concerned that you will spend a lot of cash on 64 bit windows, and a lot of time, and get nothing back for it. But if you fancy blazing the trail, I'm sure people will be grateful.
