Ur HDD storage size how big n left how much?
Coz once the storage space left till around few GB, it might slow up overall performance.
Another way to say is, ur HDD might start to slow down dy, and it could possible will KO no longer. Coz all this while many ppl do know that if use BT to download thing, it might damage the HDD n the HDD will KO early than normal usage of HDD...
Some more u open for 18 - 24 hours per day.
Recommend u few things since ur requirement to use in this way.
1. Get a better pure power supply with high wattage like 500W - 600W.
2. Get enterprise HDD, dont use normal HDD.
3. Casing air ventilation hv to be good... the air flow must good... so that it can suck out the heat...

As for my own PC since 2004 till now, every parts inside also runs well... coz i do the air flow better... Got modified my casing.
1 x 8cm fan in front
2 x 8cm fan in rear
2 x 6cm high speed fan in rear
2 x 8cm fan on side
2 x 12cm fan on side
Then PSU there got 2 9cm fan too...
Arrange the air flow which side suck in air n which side blow out air...
This is y my PC still very good condition all this while... those HDD use since 2004 till now also no problem.. coz temperature inside casing is cold enough ... nt hot...
But hv to do cleaning of dust around half a year once....
And change the thermal paste on my processor and graphic card there... so it can release the heat faster...
