This is to detail what you need to build the Microbus. The build doc’s BOM is nearly identical to what i will provide, and @lookmumnocomputer has a wonderful build video that covers the process. There is also a builders livestream as well. The video shows the smaller version, but its basically the same thing, only a bit more to do.
Here is the build doc from the frequency central website:
I bought the PCB here (US based):
You can also buy from the frequency central site itself:

I use these to lift the panel from my table, but you need to at least buy 2 screws to mount the heatsinks.
What you do is screw the standoff pins into the holes of the PCB, than you can use washers and nuts to hold in place. The screws in the pic are longer than I am recommending here.
BRASS STANDOFF SPACER GOLDEN SCREW HEX MALE M3X30MM
Quantity: 4 / 6
M3 STAINLESS STEEL SCREW CROSS ROUND HEAD M3X10MM
Quantity: 6 / 8 ( 2 are for heat sink )
NUT 3MM FOR SCREW M3
Quantity: 4 / 6
WASHER 3.3MM FOR SCREW M3
Ribbon Cable Components
16 CONDUCTOR AWG 28 FLAT RIBBON CABLE 1FT (30CM)
Quantity: I got like a few feet. Whatever is good for you.
$3.3 for 10ft
Get from Tayda if you dont need a bunch, otherwise amazon has good prices.
IDC SOCKET CONNECTOR 2.54MM 2*8 PIN DOUBLE CONTACT
Quantity: As many as needed, consider getting the amazon link if grabbing loads.
$4.8 for 16, enough to make cables for each slot. I just got from the amazon link so i would have a lot of them.

They recommend 1000mA 12VAC Wallwart, it MUST be AC / AC! I can only advise for US plugs.
This is what I use (US plugs keep in mind):
Jameco Reliapro ADU120150E1012 AC to AC Wall Adapter Transformer 12V @ 1500 mA Straight 2.1 mm Female Plug, Black
