Firstly, if you will not have high def playing capabilities for some
time, it reduces your requirements. If you will not have digital input,
it reduces your requirements. If those input-side questions will change
in the next couple of years, then consider aiming for a system which can
be a Bankend/Frontend system now, and become a backend (or frontend)
only machine in future. If you aim for a machine which can be both now
but BE only later, you might want to aim for a bigger case, with more
card slots. Since you are in the US, however, you have to consider that
ALL input it likely to change to digital in the near future: your PVR
500 card could become a paperweight, depending on your cableco!.
If you get clear digital input, an HdHomeRun unit takes no slots, only a
plug on your router.
From what you say, you probably could be looking at a minimal case,
with one PVR500 to start. You might as well go for SATA hard drives.
They ARE easier to install and deal with. I am using a SilverstoneTek
LC11M which comes with an IR receiver and remote, and VFD display, all
supported by lirc and lcdproc. At present it has an ASUS P5L-MX mb, with
SilverstoneTek Nitrogon 5 cpu cooler. (The Intel cooler which came with
the core2 duo chip was too noisy.) The Silverstone line are very nice,
and come with PSU, but are card limited and often require a flexible PCI
extender depending on the motherboard and the riser card. My PVR500
'mounts' to the third PCI slot, using a flexible extender and is the
only PCI card in the case.
I strongly suggest that you get ONE drive, anything above 20G will do,
and install the system to it. Your video storage disks are separate.
This allows you to transplant the entire system without problems: from
your old disk, you actually only need your mythconverg database, and
your lircd.conf and lircrc files to rebuild on new hardware (yes, there
are other bits which make it easier, but those are the myth bits which
are hard to reproduce if not irreproducible.) My office fileserver ran
for a year using an old 20G laptop drive as its system drive. The files
were on a separate 80G drive. The mythbox presently has a 13G system
driver and 120+250G video drives. On the system drive, make /home and
/var their own partitions.
Regarding keyboards. Logitech has a dinovo line which is bluetooth
based. A small dongle in the computer does it all. The keyboard is quite
small and the mouse has no wires!. I bought one for the mythbox, but it
ended up staying at work. I recently bought another on special from
Staples, ended up at $30 with a major rebate from over $100. There is a
more expensive version at around $180 but not worth the extra.
You can record VHS tapes using manual scheduling. In the wiki I think,
or on the archive.
Wireless will not work well *for delivery of video*. If you are thinking
about connecting the box to the net for mythfilldatabase, then that will
work.
