I don't actually have this thing online but it is fully functional. I bought it for $25 from a data center I worked at once when it was retired from service after nearly 8 years of 24-7 service, go dell! Anyway.. piccies.
PowerEdge 6400, dell's 7-u Pentium-III Beast, with 10 hotswap scsi bays.
Currently populated with 4 x Pentium-III Xeon @ 700 Mhz. Yes those are the chips with the 2MB cache on them. It supports up to 4 x 900 Mhz Xeons, but I think those are like 128 KB or 256 KB cache, so I might not ever replace these.
All those ram slots. Yes, it actually does run dual channel with PC-133 ram. 16 total ram slots, and it uses PC-133-ECC-REG. It -could- support up to a total of 16 x 1GB (16 GB) ram but it would have to run via PAE so.. not sure what the point would be. I have it mixed-and-matched with enough to come up with 2GB right now.
Expansion card area. What I didn't show in this shot is there are two green-colored 133 Mhz PCI-X slots down bottom, the raid card is occupying one, there's another below it. I have the original PERC 2 replaced with a later model adaptec 2120S that's lower profile, and jury rigged a heatsink to it, the original PERC 2 the battery died and I just went with this instead of finding a replacement, since it's not run 24-7. I added my own fan to the expansion card area, some of these cards get toasty. At one point I had about 8 scsi-160 drives in this thing in raid-0, in the PCI-X slot, and had a PCI-X gigabit NIC in the other PCI-X slot, and it was capable of sustaining a full 110 - 125 MB/sec reads and writes over the network at 99% gigabit utilization. So.. I could use it for a server if I wanted to, but right now I don't need to.
