I agree with you, I have many PCI-X server boards, they can be had cheaply
today, and perform very well, though they do draw a lot of watts (or rather
the CPUs that fit into them do).
But the OP wants to use a new server, with PCIe slots, so let's see what we
can find to help him do that.
If power consumption is a factor, this will probably be better for him.
Looking at his situation, I think the main thing is to be certain what sort of
signals the cable company sending him, and how that might change in the
Nobody wants to make a substantial investment in hardware and time, only to
have to re-do it when the cable company decides to go all digital.
If it were me, I'd start by sitting down with a cable company exec, and finding
out what their plans might be, assuming they even know.
Since his new server has gigabit NICs, perhaps multiple HDHRs would work, if
the channels he wants are available as clear QAM, and will continue to be.
This will remove any dependency on a particular type of slot.
