My first emulator pc build

[Budz71]

Hello everybody. I've been doing a ton of research for a hyperspin arcade cabinet build and I have the cabinet design down but I am struggling with the pc build.  I will be running Hyperspin along with emulators for Atari classics, NES, SNES, Genesis, N64, & PS1. Maybe a little PS2, Gamecube, & Wii as well. I would like to pull some money out of the build if anybody has any suggestions. Here is my proposed build along with questions:

My main questions are:

Is freesync really needed for what I want to do? From my understanding it really helps with older games which is the majority of what I will be playing. Without freesync I could shave a fair amount off of my GPU and Monitor.

If I do away with freesync how cheap could I go with my graphics card?

Is a 240GB SSD enough? Should I go with a larger 3.5" drive instead? Or a smaller SSD paired with a large external drive?

If I go with an external drive will I have problems playing games because the data transfer is slower?

Any other suggestions would be helpful. Thanks in advance.

3-5 Tb is the sweet spot if you want all the systems. I5 unlocked is perfect, 8 gb memory is good. You need lots of cpu not cores. 3.5-4.5 is what you want to shoot for so you will be overclocking as well. 500-750 watt psu
