The room ambient temperature is less than 80 degrees F. All 6 internal
fans are working and the cpu temperature is less than 100. The box
temperature is less than 85. The Box currently contains 2 60 Gig Maxtor
drives in a RAID Mirror configuration used for all programs, a 160 Gig
Western Digital Drive for data, A DVD Writer and a DVD Reader, A 3.5
inch Floppy drive, the mother board (for the past year) is a Gigabyte 7
with onboard drivers for RAID, 10/100 ethernet, USB, Firewire, and
Audio. There is no accumulated dust, as I have used dry air to blow out
the dust about once a week. The computer is used primarily for Adobe
Photoshop, followed by web surfing and gaming. The area the computer
is in also has a large room fan blowing directly towards the computer
when it is in use.

The most recent failure, about 3 weeks ago was the DVD Writer. The
motor that spins the DVD failed.

The failed motherboard was a Soyo Dragon Ultra, and the caps around the
CPU literally blew their tops. This was last year in August. It
followed the original power supply that blew out in July almost 3 days
after the warranty period expired.
