and aren't 5400 drives a *lot* cooler?
I 've made the mistake of buying a 7200 SATA disk and they run hot!
Which means I need fans which means noise...
Luckily this all got kicked off because the wife said she wanted a PVR
and offered to donate her PC as a test bed ;)
What we're doing now is bodging it together in her PC (which we'll
restore at some point) and then once it's all going we'll buy a
mobo/case etc for a dedicated machine.
I'm now thinking lower end CPU (but not *too* low) with passive cooling,
variable speed psu, 5400rpm disks (probably multiples), old VGA card (I
may try the VGA/RGB hack at some point) and a sound card with SPDIF.
