Pulls air from front to rear thru the SBB (storage building block)

You are not supposed to get your hands on them... Newer SBBs have
'warranty void' stickers on them to keep people from opening them.

If you want a really fragile flex check out a TZ8[67] DLT tape drive
in an SBB. But kidding aside: you need to be careful with the flexes,
but apart from that it works just fine.
