You switched two wires.
Judging by the craiglist watermark on the bottom right, it’s probably just a meme listing.
I have stolen it from Chinese website
Haywire. You don’t see that often anymore.
I wonder why

Oughta be able to render hair well at least
also doubles as an electrical fire generator, very versatile
If you are worried about that, then don’t look behind the panel on any computers with a wire wrapped backplane.
The design is very human
This is apparently what the front looks like.
Wow even looks like a GPU.
Socks outside vs inside
What is it?
Dedication to wire this up manually is amazing.

Are homemade PCBs really that effective? I’d wanted to try my hand at them but never could settle whether it was worth attempting.

With the rise of inexpensive 3d printers, I wonder if milling would be a cheaper option.
We had a PCB mill at the university I went to, a “few” years ago.
Only as effective as your layout skills :)
Check out jlcpcb. Honestly insane what is available to the hobbyist of today
My understanding is you make fewer but more replicable mistakes. If you use a wire you have to trace it, keep the length consistent for timing reasons, use very consistent soldering technique, and ultimately you have a hard time tracing issues. With a homemade PCB you generally do get what you ask for in terms of circuitry. Traces are the right length, right thickness, right spacing, and if not then the whole board is similarly impacted, so it is obviously broken or not broken. If you mess up your design then you have a problem, but if you did the process right and you have a valid design then it works.
That all said, homemade PCB is a large time sink and modern PCB manufacture is so cheap and fast it doesn’t make sense to do at home for the most part. You can literally get a complex board faster by ordering it from halfway around the world and having it posted than making it yourself. I would say it is a good learning exercise, not a good manufacturing or prototyping practice.
Messy cabling. Pull them out.

Typical spaghetti code
-O2 from the looks of it
Mine almost looks that good
nice

Me when I forget about FPGAs
And the fact that more-than-0-layer PCBs exist
What am I looking at?
It looks like a wire wrapped prototype board of some kind, impossible to tell the purpose from that photo alone though.
I don’t know, maybe it’s not even a GPU
Did you see the pic of the front?

Looks like an ISA card to me - might be RAM, but I’m not confident at all
Serious response I agree with Pogo, it looks like a handmade RAM.
some pci-e device. but the main chips are probably on the other side of the board.
A free and open source GPU compiled by hands
The free and open source comes with the fact it was hand made ? I don’t get it
I don’t get it either
The joke is in the eye of the beholder, for me it’s funny because you have the buzzwords “free and open source” which means you can implement it however you want and the user here decided “fuck it, I will do it by hand”.
Would assume that in this case that the gpu was created and assempled using a open blueprint/schematic thats freely available for anyone to see use and modify. Fairly common thing when it comes to stuff like 3d printing where many people freely share their models for others to use.
What’s its name

GTX Firebomb
aka FTX (F for Fire and to pay respects)
Is there more info about this? I could only find Chinese forums like https://m-weibo-cn.translate.goog/status/OdaBMza1L?from=page_1005052963774131_profile&wvr=6&mod=weibotime&jumpfrom=weibocom
The chips (basic TTL logic, perhaps) are all DIP. This may predate the term “open source”.
