That’s really an adequate system for what I read as the requirements. However, HT, if you do go that route, make sure that your monitor can connect (given its age I’m guessing it’s VGA) or purchase an adapter, and make sure that your keyboard and mouse are USB or purchase an adapter for those too. These don’t cost a lot of money, and I can tell you that unboxing and setting up your new machine can be infuriating if you get all the way to hooking up the peripherals and find out they don’t fit! So then it’s schlepping back to the store and buying a cable or adapter or whatever. Not that it’s ever - ahem! - happened to me... ;-)
Thanks so much, I feel awful that I didn’t mention no monitor and no VGA plug! I’ve had my computers hooked to a LED TV for a decade and must say I’d forgotten all about people using monitors.
