Attractive, but as with all HTPC-style cases, heat will be an issue,

Probably not overkill for all you're talking about running, but again,
heat wlll be an issue. This much power would be overkill in a more

Certainly overkill for Myth, but should make transcode jobs fly by.
But to put this in perspective, I use a P4 2.5 GHz, and it manages com

Definitely overkill. Anything more than 512 MB is icing as far as Myth
is concerned. You may notice a performance boost but I really doubt

Again, running four drives in this case will generate a lot of heat.
Are you really sure you need this much storage as you're starting out?
Keep in mind that SD records at around 2.2 GB per hour and compresses
down (with good quality) to around 750 MB per hour.
I would seriously think about setting up your machine with only one of
the 500 GB drives, and maybe a small (20-40 GB) IDE drive for /,
/home, and swap.

You will definitely need a CPU and ambient temp reader, though I'm not
sure you'll like what they tell you.

Double and triple check the compatibility of this card under MythTV.
Or save yourself a lot of headaches and get an nvidia. Again, you
don't need the latest and greates. Fx5200, or 6x00 series are golden.

Not necessarily the best if you're bringing one feed direct from cable
and another from an STB. Not sure but IIRC, you'll need the expansion
module, which will take up another card bay, if you want to use two
seaprate inputs for the PVR 500's tuners. It may be worth getting two
separate PVR 150s (although I could be wrong on this one).

This may not be what you want to hear, but you'll be much, much better
off, and save yourself a lot of headaches and likely a bit of cash, if
you go with two machines rather than one. Make one box a dedicated
Myth machine. Make another one a desktop machine. For the budget
you're talking about you could easily do two machines and not lose any
of the capabilities you're talking about.
