Or even build the computer yourself. Outside of the graphics card shortage a couple of years back, it’s usually been cheaper to source parts yourself than pay an OEM for a prebuilt machine.

A small side note: If you buy a Dell/Alienware machine, you’re never upgrading just the case. The front panel IO is part of the motherboard, and the power supply is some proprietary crap. If you replace the case, you need to replace the motherboard, which also requires you to replace the power supply. At that point, you’ve replaced half the computer.
