Nintendo Gamecube PC (planning)

[Jacksonyoung]

Budget (including currency): $500

Country: USA

Games, programs or workloads that it will be used for: Rocket League, Divinity Original Sin 2, Forza Motorsport 7, Halo Master Chief Collection

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): 

So the main issue seems to be locating a Mini STX motherboard. The dimensions of the Gamecube are too small for Mini ITX. Combine Mini STX with COVID-19 availability and it was resulted in difficulty in locating a Mini STX motherboard. eBay and Amazon are dry. I found one via: https://www.shopblt.com/item/gigabyte-ga-h110mstx-hd3-h110-dp-lga1151-i/gigmbd_gah110mstxhd3.html. I've found 6th/7th gen Intel CPUs available on eBay and I have a Pentium G4400 laying around that I can at least boot up the computer with. I can source the rest of the parts (dremel, DDR4 laptop memory, M.2 drive, SFF cooler if Intel cooler won't work for various reasons, DC adapter). I guess my main questions come down to:

1. Will I be able to find a graphics card that will fit this thing? Most graphics cards I can find are ~ 170MM in length and the Gamecube is ~ 150 x 160 x 110. Even the low profile GPUs seem to be longer than SFF cards

2. Will waiting out COVID-19 even be fruitful for finding Mini STX motherboards? Supply seems low and I'm not sure what regular pricing is. I know Gigabyte/Asrock/Asus make Mini STX boards, but can't find any new other than the link posted above. There was a part on two different Mac websites that says "unavailable" after you attempt to buy it for ~ $40 US.

 

Any thoughts, comments or suggestions would be greatly appreciated. I've found other threads on sites talking about building PCs inside of the Gamecube.

 

Computer will be hooked up to a Samsung 4K TV. I currently have a computer using an i3-4370+GTX 1650 hooked up to it. Works fine for 1080p, though I can crank up to 4K for older titles.

There is cards that fit but those use micro hdmi or something simlar and are not really that good and i would suggest trying to opt for an amd cpu even if the intel cpu is used brand new amd can be the cheap price and better performance

I agree with @Kanna. I've seen others here buy the ASRock DeskMini A300—it's an AM4 socket which officially supports all the currently available Ryzen and Athlon APUs. I'm not sure whether it'll support a non-APU or not; they don't include any in the support list, and for good reason. Due to the small size of the mini-STX board, there are no PCIE slots, so a dGPU isn't officially supported either. However, there are two M.2 slots, and you can get an M.2-to-PCIE adapter to plug in a GPU—just be aware that it'll be limited, at best, to PCIEx4, as that's the width supported by M.2.

Still, at 200 USD, that's likely to be your best bet for a modern mini-STX board. It's just not a very common form factor.
