Yes, the nice thing about a ‘tower’ assuming it’s not a micro atx case is you can put a few drives in it, and swap out various components if you want.
With a laptop you’re pretty much stuck with what you’ve got aside from adding second ram stick.
Laptop processors are also generally cut down versions of thier desktop brethren, to extend battery life on the move.
So maybe consider first, if you really need the portability of a laptop.
But an SSD system drive is really a must for general use. A lot of the cheaper laptops on curry’s /PC world don’t even have SSD.
The current ‘high street’ trick seems to be offering a reasonable cpu and ram, and a *1 terabyte hard drive!
*hard drive is a 5200rpm record player.
