[Working, Never-Serviced Centris 650] What do I need to fix/replace before it explodes?

[sinisterpisces]

Hello,

I've got a Centris 650 that I know turns on and works--or at least doesn't have a problem that I've found yet. The previous owner showed it working and fitted it with a Zulu SCSI, but I've not yet turned it on or plugged it in because I'm not sure if the PSU has a RIFA in it.

However, I suspect that, aside from replacing the battery (with another battery that can leak), it was never serviced by the previous owner.

So, I'm trying to figure out what I need to address before something potentially explodes, leaks, or otherwise damages the system. Am I leaving anything out of this list?

1. Replace battery with coin cell (with an adapter of some sort).
2. Replace or recap PSU. The potential for cap leaking aside, I live in a carpeted apartment with windows that don't open. A RIFA blowing on me would be an actual catastrophe.
3. Replace or recap the CD-ROM. I'm pretty sure this will have caps on it that will leak or have leaked.
4. Replace or recap the floppy drive. Same as above. Though, I like the idea of replacing it with an internal BlueSCSI.

Am I missing any obvious potential explosions/leaks?

Thanks!
