should last six years. Failures are basically a random luck of the draw issue beyond our control after we assembly the items without reducing their reliability.
It may be a trick question, in that the CMOS battery life is not that long and fans usually don't last that long. Also the newer burners have short lives, however it is very unlikely that there is anything that you can do about it.
Just use dual ball fans.
Hard drives have about 5 years of operating life before wearout starts, however that's 5 years at 24 hours per day.
Solid state devices wearout is in tens of years.
The other catch is a design which assures that the components all run at their design temperature. Again, the loss of a cooling fan can kill the entire system. A power supply rated about 25 to 30 % higher wattage than the components consume helps the power supply capacitors live longer. wattage
OK: this is for my Computers class project. Purpose: to build a computer from scratch that will last a home user (not a heavy gamer) for at least 6 years, hopefully more. Not cutting edge people, but not too far behind either.
The budget is $1,100. Some of that has to go to other hardware, like a vidcam, headset, DSL Modem, etc. Some has to go for software, such as Antivirus, firewall, OS, office suit, etc.
I haven't figured out how much these items will cost, so I need to leave myself a buffer in the budget.
For processor and hard drive I chose 2 options, figuring that my user doesn't need the high end version, but if they have it, their computer will last longer.
There are two configurations, using the higher and lower end versions of the components, with two drastically different subtotals:
1. Gigabyte GA-k8nf-9 ($76)
2. MSI k8n Neo4f ($70)
1. POWERCOLOR R96-D3G Radeon 9600PRO 256MB 128-bit DDR AGP 4X/8X ($79)
MSI FX5500-TD256 Geforce FX5500 256MB 128-bit DDR AGP 4X/8X Video Card ($75)
2. should I spring for the more expensive Sapphire Radeon x1300, ($95) and if so, why?
1,2. Sony DVD and CD burner: Model #: DW-Q30A BK NO/SW ($38)
Sound card: skip it unless there?s lots of extra cash at the end.
1,2. Antec Sonata II, since there is no significant price break from the Sonata I and it has a better power source ($98-$99)
(May shave money off by getting a diff. case. Can anyone reccommend one with a 450 watt power source for cheaper?)
1. AMD Athlon 64 3200+ Venice ($156)
2. AMD Athlon 64 x2 38oo+ ($322)
1. Western Digital Caviar SE 80 gig SATA ($55)
2. Maxtor Diamond Max 160 gig SATA ($90)
1,2. 17" LCD ($189)
May shave off here by using owner's previous monitor, be it CRT or LCD.
The total for version 1 is: $685, leaving me plenty for software and peripherals.
the total for version 2 is: $908, meaning that I may have to rely on freeware.
Or, I could combine the two, choosing the best for the more essential components.
Speakers, keyboard, and mouse I'm assuming my user has already and does not need to upgrade.
