I couldn't boot after putting in a new 400GB hard drive in with a DVB-T card
because my 90w external brick power supply couldn't handle it. Worked ok
with a 120GB.

To help reduce noise I oiled the cpu fan and attached a 47 Ohm 1 Watt
resistor to red connector of cpu fan. Fan 12V .09A 6300rpm now with
8.9 Volts across 5120rpm. My case has two 4cm extractor fans which reduce the
risk of overheating.

VIA have been putting out fast models with fans and slower version without
fans based on the same generation of cpu. The more recent version use
smaller transistors sizes which reduces the heat.
I'd have a good look at there range and what support OpenChrome has before
buying. Better, fanless and maybe both are available for a few bucks more.
$210 is cheap for HD now and saves replace the whole system later.
Anyway your choice,
