Can you run multiple mobos off one power supply??

I was wonder, as I have a whole box of assorted pentium 1's (although I still have to gather up the processors around here, I also have an old p2 sitting here somewhere). I only have a few power supplies, and really, getting more power supplies isn't a problem, but they can consume a bit of power all together. I was wondering how many motherboards it would be possible to power off say a 300 watt power supply? I was thinking of splicing some additional mobo power connectors in off other power supplies. I want to just run these all open and don't plan to use them for much more than giant hard drive controllers (4 hd's to a mobo isn't that bad, wouldn't take up much more space than 4 external usb drives).

. You should be able to run multiple mobos with one PSU, but I've never tried it. Spinning up 8+ HDDs will be rather taxing for a 300W PSU. . Use large wire (14-12AWG) for long runs (> 2') to lessen voltage drop. . Solder all splices. . All in all, you'd probably be better off using dedicated PSUs. Especially if you want to run four HDDs/mobo.

Well, I would only use the psu for the mother boards, and then find a couple more for the hard drives, and one for the cd/dvd drivers. I still think I could reduce the amount of power I use for say 4 motherboards.
then you may do something with a 12.5 V supply that aids the startup and then shuts down then yea it'll be ok and better than supply for each board if you use old supplies keep in mind that their power capacity is way less than written (aging electrolytic capacitors) and why you want it all instead of 1 new drive ? it'd be better to use the computers for thin terminals and not storage

the computers aren't very powerful (120-233mhz) so they aren't much use at all for a thin client.
why ? it runs decently lightweight desktops on its own without even being a client. if you turn it into a client it can make good performance

Actually..I was watching a video the other day on youtube of steve jobbs showing 50 imacs connected to one G3 server, each booted, and playing videos off one 100mbit ethernet connection (astounding at the time I guess). i have this G3 here now, but I can't install osx server 10.4, and linux is a flop over, what do I do?!?
whats the problem with linux ?

can't get past the boot screen (seems to be a added feature on a lot of computers I try linux with).
did you try various disks of linux ? some linuxes have compatibility issues with specific computers are the disks intended for the mac computer ? you cannot run PC disks on old mac

I had downloaded Gentoo for PPC, it should have worked.
