The OP obviously has little to really learn from anyone who questions his plan, and I'm surprised that someone who purportedly is of a scientific bent rushes headlong into a project without what one would assume would be the requisite research and logic abilities of such an orientation. But here's something for others interested in "upgrading," "building," or other similar projects.

Simply installing new parts on a bike is generally a straightforward process, something that occurs relatively rarely, and can involve tools that also are rarely needed. Also relatively rare (and time intensive) is the need to spec compatible parts, especially for an older bike. So the learning involved is very little compared to the time invested. Adjustment/repair is where most of the learning takes place, and more so on used parts rather than new equipment.

One can of course say that the cost is not that important, but it's a bit of a waste to spend money on parts that will only fit an older bike, and one which very, very few would be interested in buying at all when one truly wants to upgrade to another, let alone for more than about 1/3 of the money being spent. The better way to learn would be to purchase one or two more modern bikes in better condition and then replace parts only when the originals are not functional or do not meet one's needs AFTER riding the bike.

Putting new components on a frame is especially counterproductive because such a frame has limitations both in what can be installed and in performance. TO THE OP: You said on another post you don't use your laptop much any more and got a Surface instead - let's say you've never worked on a computer before and have an older laptop - why not upgrade the hard drive, memory, put in a USB 2.0 pcmcia and wireless N, maybe a new screen, etc for the experience?
