I don't understand how people can recycle their computers and not lose money. Sure, there is eBay, but in my experience it's hit or miss on resale for computers like the Mac Pro. I bought my 2.66 and about 6 months later took a look to see what it was worth (see what people were paying for them on ebay). Even though I had upped my ram and added 3 more drives, I could see that I'd lose around $800 maybe more selling on eBay. Then to buy a new replacement machine, it would have easily been $1000 out of my pocket for trade in. I decided then that my computer was worth more over the long term as a backup machine or renderbox than to lose money reselling it.
