Mines going in a cabTook me a few hours to get my head around things with the clone
I bought some bits from Amazon and it worked well so far, the usb controllers are it bit naff but I can put 3-4 USB items on the hub okay and power supply seems ok with it.
I used my computer to copy update_all script and the boot system MisterFusion and away i went
'TRIXES Pack of 2 Wired USB Controllers' - needed something to control with and my USB keyboard helped too.
'SanDisk 128GB Extreme microSDXC card ' - seems big enough
'100W USB C Power Adapter Fast Charger for Mac Book Pro 16'' 15'' 13'' 2016/2017/2018/2019/2020'
Jamma connection powers it ( I hope )
