I have used these a few years ago for aesthetics inside my old computer.
Not sure how broadly appealing these are, but at $1/pop they're very cheap.
Xigmatek iCable VGA 6+2 Pin Extension Cable $1
Xigmatek iCable CPU 4+4 Pin Extension Cable $3
Xigmatek iCable Motherboard 24 Pin Extension Cable $5

Also, I got mine yesterday they are pretty good but they are really spaced out so like if you just want something cheap its algs but they aren't the best looking :) still cheaper than AE ;)
Thats a good price for those extensions, they aren't the best and have gaps in them but compared to the most basic ones on aliexpress (which these are as well) they are actually a very good price. Like 2x pcie 6+2 is $2 and 1x 8 pin CPU is $3 and 1x motherboard is $5 so only $10 for a whole set. Aliexpress ones are usually like $19 incl gst and shipping so you know not bad. :)
