Re: Ventilation/cooling of PCs

["paul gordon" <paul_gordon@xxxxxxx>]

I agree the price differential between SCSI & IDE has narrowed in
recent
years, as has the performace differential, but it is still significant. As
an example, I mentioned I just purchased a 17.3GB Ultra-DMA66 EIDE drive,
this cost me a grand total of £144 (Inc VAT & delivery) from DABS
direct,
the cheapest SCSI drive I could find of a similar capacity came to well
over
£400!! Likewise, decent SCSI controller cards are a lot cheaper nowadays, -
I recently bough two Adaptec PCI cards for about £55 each as I recall, but
I
think I can safely say that they'll _Never_ get as cheap as EIDE
controllers: (FREE with any new motherboard!)

BTW, I still think the performance of SCSI is way ahead of EIDE, so IF you
can afford it, or justify the difference, I think it's worth it -
especially
if you have a large CD collection to rip - SCSI hardware could potentially
_halve_ the time required to do it...

Regards.
