I'm planning on turning my old AMD machine into a Linux fileserver. I cracked it open today just to take a look at some of the hardware. The thing that I was most interested in was whether or not the power supply and MOBO could handle 3 or 4 HDDs. Taking a look, I've got SATA connections enough to support the drives, but I'm concerned that the 510w PSU might be pushing it for that. Anyone have any opinions on this or maybe some references I could use to figure it out? Keep in mind that this is an old Athlon 64 cpu. I'm gonna take out one of the gfx cards and leave it with a single 6600gt. Also, it has an old SoundBlaster card.
