That is, define the needs the device is to meet. That allows you to determine the hardware, operating system and software required. From there,one can add RAM and storage option upgrades, video card enhancements, etc. and so forth.
If you examine the files saved on your friend's old computer, that will give you a good idea of what he/she uses the device for. Add to that the current "wish list" ranked by importance/value to the intended end-user.
If it turns out that an off the shelf Laptop will suffice, you'll have the specs requisite to effectively putting out a "Request For Proposals" or shopping pecs sheet.
Then go looking for suppliers and deals on price, quality, warranty, service, etc.
