Ah yeah, that slot measurement could actually be an issue (I've previously noticed that those would still fit when you use some light force), since the pitch would also apply to the cards being used (I do intend to use a SMUC + GS on a Scorpion).
Personally I don't mind assembling computers myself, but i'll double check in case there are any ICs which are hard to get (1533 are virtually impossible to get here and the 74ALS counterparts are sometimes quite expensive) - thanks for the offer
Any timeplan yet, when you'll have the PCBs ready?
