Must be 20 years or more ago since I repaired one, but I think there are
a couple of capacitors on the video board that are the first things to
go on a Mac plus.

Secure erase overwrites the drives multiple times to ensure that none of
the  original information is retrievable.

The drives would be SCSI-1 (5MB/s), there are cables/adaptors that would
do it, but I do not have one anymore, ebay is probably your best bet to
find one. Do you want to copy the data off the drives before the secure
erase? Do you happen to know if they are formatted MFS, or HFS? I don't
know if there are MFS drivers for linux, but one exists for Mac OS X
(readonly, Apple sample code)
http://developer.apple.com/samplecode/MFSLives/index.html. Perhaps
someone on the list can lend you a cable, if not, I have an older
powermac g3 that has a scsi interface (but I do not have any scsi
cables) that you could borrow to do the copy and erase.
