I would like to buy a PC that would be encoding for long periods of time, encoding a video after another.

I would like to know what specifications the new computer would require.
for example,

More than a GB of Ram?
Video Card / Graphics Card ? - and what's the difference between them?
Minimum Processing Speed.. Is 2.4 Ghz ok ?

I would like to know if there are any risks of encoding for long periods of time without having breaks? - I'm using TMPEGEnc (Very Slow Encoding)

Would the hard disk heat up too much?
If so, would I need to buy a stronger Fan ?

If anyone has any suggestions or recommendations,

I would really appreciate it,

Thanking in Advance,
