your computer
is it a laptop or desktop one. was it shop bought -built for you by a company to your specification or second hand? or even built by yourself. Was it built for a dedicated purpose , in my case for photographic work mainly
I, with sons help, built mine in 2012 to a budget of Just about £1200 . Started out on windows 7 but upgraded nearly everything since then. lets see what did I upgrade?
from windows 7 to windows 10
Power unit from 350w to 750w
changed cooling fans to quiet running
changed cd/dvd player
new sound card
changed graphic card
from 8 gig of RAM to 16 gig of RAM
HHD "c"drive t0 SSD drive
added another HDD drive for storage on board and 2 TB extrnl HDD second backup drive
It already had several USB 2 and 3 ports which were enough
Like any desktop home built computer, , one is always, or at least I am, upgrading components,. Either because they stopped working - don't work on newer platforms or adding parts for improved performance.
it in fact 3 months spent selecting which bits to get For example I wanted a computer case that had input fans on the front and extractor fans on the back for a straight through cooling unit. Many have to extractor fans on the side slowing down air flow. Each component was chosen not necessarily the best but what the budget for that component allowed for
Therefore when I built mine every part was costed to comply with the overall budget at the time.
My initial thoughts were should I go for a pre-made one from a local shop- go to a specialist computer company that built to a spec- or build my own. It all really came down to cost and what I got for my money. Building ones own you know what is in and your not paying for build costs a company charges
