So I've been updating the inventory and here are the relays :

That's approximately 3000 relays, so I'm good.

I also have 10 capacitors (100µF 25V) but the sizes are mixed (4K in 6×7mm and 6K in 5×11mm). This does not help making a compact DRAM board, I'd like to fit 16×16 in a 10cm square... 16×5mm=8cm so I have room for connectors on 3 sides.
