Matt Millman blogs about two designs which provide additional PCIe slots in modern computers.
The first, above, is a small form factor OCuLink/U.2 To PCIe X4 adapter.
Some time ago I designed an “as small as possible” adapter to make use of spare OCuLink/U.2 ports that are often seen on PC motherboards these days. There are of course ready made products which more-or-less do the same thing, but they were all oversized, awkward and difficult to incorporate into an small form factor (SFF) build.
OCuLink is an extension for the “cable version of PCI Express”, acting as a competitor to versions 3 and 4 of the Thunderbolt interface. See this on GitHub and the blog post.
Second is a PCIe Bifurcation Riser,
I designed a couple of PCIe Bifurcation risers to solve some difficult build problems I was faced with, namely fitting a second PCIe card into a case which was only designed for one.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
