Don’t know if this will work for you but I’ve been using this rig I made for several years now. You can customize it to fit your needs… I kept it fairly small, but if you want a patchbay you can mount it under the metal laptop plate (I put a wireless guitar receiver there) or just get a slightly larger case. I put my Scarlett 2i4 under the laptop plate, so all the connections are easily accessible in back. Best thing about it - it’s fast. I can be set up and plugged in within about 60 seconds.
