Hi Paul,
Well, we bought two Dell's for just the LS cards, non PCI-Express. We didn't need the HD because our cameras can't do it yet, but we did need the digital audio inputs.
For the third computer, we're custom building it for the LHe. This includes the Tyan Tempest you have, but I am thinking along the lines of some Enthusiast kit, a Lian-Li PC-V2000 and a PCP&C Silencer 750W PSU.
But, now that you've mentioned it, the Intel case is pretty nice, and less expensive. In reading the specs,
here, it's clear that Intel adheres to the SSI standard, which includes EPS12V PSU's. So, the Tyan should work beautifully. Now, the next question is whether the Tyan board can control all the fans in the SC5400, which the answer is yes, of course it can.
Good luck!
Cheers,
Brann
