Given your present system, it sounds like you are talking about a combined BE/FE machine.
In the US, the HDHR and the HD-PVR are common for HD capture. I'd keep the PVR-150 for capturing the SD output of an STB
or satellite receiver, and any analog channels you might still have access to on a cable system.
The HDHR is good for any OTA stations, and any clear QAM available. The HD-PVR is good for capturing the component HD
output of an STB/sat receiver.
You might give serious thought to a separate BE and FE, which allows for much more flexibility and upgrade potential to an

Kind of hard to find new machines that are not at least dual-core these days. The software support for multi-core will
improve with time, and you won't save enough money by getting a single-core CPU to be worth it. The exception is FE
machines like the Atom-based ones, but even they are trending towards dual-core.
Think about if you want to use your main machine, or dedicated BE if you go that route, as anything else, like a household
NAS server, and how much disk capacity you might need. If you want to run VMs on this machine, take that into
consideration as well.
I believe in the "central machine" concept, but others like the separate small low-power boxes approach. It's up to you,
and highly dependent on your needs and budget.
