How old is your computer? If you've upgraded it then use your own judgment. If it was a RAM upgrade then I'd just go with the purchase date (if it was new when you bought it). If you upgraded the motherboard and CPU then you could definitely say it was "new" the day you did that. So, how old is yours? Mine is probably about 2 years old. I've noticed that it's still comparable in specs to some of the cheaper new computers. I won't upgrade it or build a new one for at least a year, if not longer. I would like to SLI my video card though if I can find a duplicate card with the same specs.
