Yes, it would make more sense, and the desktop PC can have better stuff for the same amount of money. You can always get the main components first (motherboard, processor, RAM, power supply, etc.) and, as you get more money, get the rest later.
That's what I meant. I want to buy everything at once since prices can go down and I don't want to buy something now that will get a lot cheaper in a few months. Maybe I'll be able to upgrade this PC I'm going to buy first instead of buying a new one in the future. It depends on how long I'll be able to wait to raise money. My current PC is very old.
