Depends, which cords? The typical computer has any number of cables going into it, but only the AC power cord itself would have the gauge of conductors to carry
But, considering these cords are generally only 6ft/2mt long, thats not much of an extension, not to mention you would have to cut the end off and replace it
with an electrical socket / receptacle.
I've converted bad flatscreen VGA monitors into lamps. Specifically ones where the backlight works, but the screen wont come on or the LCD is damaged/cracked.
Basically take the cover off, remove the LCD screen and filters from in front of the back light, then put the cover back on. You basically have a bright white florescent
panel on a stand (or the light source and power inverter can be removed and built into a different case.)
Since the many of these old monitors run on 12VDC, these would be great for battery/solar systems.
Computer power cords aren't good for much of anything else, it would cost the same price to fab it into a 6' extension cord as a 12 ft extension cord. Though the wire gauge is usually pretty good.
The fans are good for many projects; I've made circulating fans for the tent, a cold smoker, a biltong and herb dryer etc.
The platters from the hard drive make decent mirrors, wind chimes, signal devices. I mounted one to the back of my cell phone so I could view the back of computers, the flashlight illuminates the target and the platter mirrors the image back to me.
Magnets from the hard drives are useful for many projects.
Speakers can be handy for projects.
The wires from the power supply are a decent gauge and similar to that used in automotive applications.
The power supply it self can be used to generate 5 or 12 volt power (I suspect it would be a waste compared to other methods)
toroids can be used to create joule thief devices
Switches for power and reset are useful, the 120/220 power supply switch can take mains voltage.
CD/DVD drive motors can be used for assorted projects.
The laser from a cd/dvd might be useful if you're into that.
Many motherboard parts are useful for breadboard applications.
Speaker and microphone jacks are easy to reuse for low voltage applications or audio
I've reused some of the plastic by softening it with acetone but I wasn't impressed with the results.
The metal pieces are pretty useful but they take a considerable effort to refabricate.
The clock battery and an LED could make a flashlight of sorts
... those are the easy ones off the top of my head.
