So none of you ever replaced the parts after buying ? Cause that's where the tricky part is... I can logged the purchase date of the unit... but the parts invalidate it cause old unit with new parts is neither old nor new...

An old Computer with new parts, is simply refered to as an upgraded system. If you buy from a large vendor such as hp, Dell etc, you can purchase hardware upgrades from the vendor without voiding the warranty. It would be advisable in the future to build your own PCs if you have the experience, if not contact somone you know with experience to help you. Keep in mind most vendors offer a three year warranty on parts (Read the fine print) and one year support on the OS.

Most refreshing to have perspective from the other side of the fence !

Suppliers are notoriously very good in estimating warranty time... most of the hardware we got dies like weeks after warranty period expires. How do you guys do that ?
