The board really only has one pci slot, there is a riser card that won't fit that will turn the one pci slot into two but it won't fit in the case with the board and so on. I have one agp slot and one pci slot so I figured agp video card and the pci slot would be the ide controller...
When I put the card in I get all kinds of "Plug and play configuration error" messages. I think it has to do with the irq settings between the onboard lan, sound, video and so on... conflicting with the card...
Tried screwing around with all the settings in bios, but nothing seems to help. I'm content with just pulling the card and using usb to ide converter cables.

Tonight I'm working on the power supply stuff. I have to add a bunch of power connectors. The AT power supply only has 3 hard drive power connectors I think... I had some y-splitters before but can't find them, so I'm just going to use some power connectors taken from a couple of dead power supplies I have and wire up my own ghetto way. I have some black tape and shrink wrap, its farily straightforward so long as I follow the right colors should be fine.

So 3 power connectors will soon become 10 power connectors. This is the first step towards getting all the hard drives installed and powered on. Afrer that I will be stalled again waiting for usb to ide adapters, hd long cables and the usb hubs I ordered...
I'll have 14 usb ports if the two 7 port hubs work. That should be enough...

Here is some more geek porn for you....

http://haywirepc.homestead.com/index.html

I mounted some hard drives, the AT power supply is rewired with 12 hard drive power connectors, power switch ghetto mounted. The computer powers up fine,The first 3 hard drives, which are connected just by the motherboard ide controllers, and the cd-rom are all working.

Next up, floppy, front face plates, then on to internal 10 port usb hub, then hard drives, hard drives, hard drives, all connected via usb to ide adapters.

This has turned into quite a project. Like most things, I thought it would be a quick project. I'm ordering the 10 port usb hub and some more usb to ide adapters this week. (I only have 4 now, those things get expensive when you need 10 or 12 of them. Once I have those, I can finish the beast. Gotta also find some case badges and odds and ends to finish her off.

I may also add a usb connected media card reader on the front panel so I can use my digital camera's memory card and so forth with my linux machine.

They seldom are.  Grin  Looks like you're having fun with it. Remember to keep a fire extinguisher nearby!

Haywire,

I enjoyed your web page describing your building of a server.  What is the main difference between a server and a regular personal computer?  We occasionally get servers in never_stop_learning's computers for kids program.....long wide and narrow boxes with fans that make a lot of noise.  I tried loading VL 6 on one of those servers once and got nowhere.  Ended up turning the thing over to Computer Corps.

Servers are designed to remain on for extended periods and "serve" multiple users at the same time. While the specifications on a server may seem "low", they don't need to be outstanding as the server is designed to serve information.

There are a couple real differences, but not many.

One servers usually use ECC RAM vs non ECC RAM. That can really raise the price.

Most servers use SCSI drives, however newer servers are using SATA as well. The
SCSI drive are designed to run and are usually faster at read/write functions. The
use of SCSI will allow for alot of HDDs without the limitation of most MB of 4 IDE
channels. Servers use a redundant power supply for fault tolerance.

Hope that gives you an idea.

Smiley servers can be almost anything.

I administer a number of servers, mainly internet gateway/file server boxes for local small business. 15 at current count. The hardware ranges from three 2U IBM rack mount servers (dual Xeon CPUs, 16 GB of RAM) to a Mac Mini which lives in a cupboard and handles the mail for a company with about 30 employees. Quite a lot of the others are low-end P4's, mainly HP/Compaq small form factor boxes. All running SME Server (based on CentOS) or, for internal file servers, Amahi (based on Fedora 12).

My home server is currently an old AMD Duron 1.6 GHz machine, though it due to be upgraded to something smaller and more modern sometime soon, I hope....

My idea for this project was for a file server, but also since I'm very short on desk space it will also be used as an extra computer. It will store all my personal files and I will back up to it from my other workstations (2) currently. If I can't find something on the workstations, I can have it on this server too. Basically, it will be a data dump for graphics, music and video projects.

I also just like the idea of a computer with like 10 or 12 physical hard drives for organizational purposes. Never had one computer with so many hard drives, so I can have one drive for graphics, one drive for hundreds of dos games and programs,
one drive for video files, one for amiga programs and games,one drive for mp3's, one drive for drumloops and sound samples I use for music production, and so on.... Like I said one big data dump. I'm broke or I would order the USB hub right away. I need the 10 port usb hub, and 8 more usb to ide adapters. Everything seems to be working so far, but I don't have the usb hard drives hooked up yet. I'm not sure if that power supply will power 10 or 12 hard drives, but I think so.

Nightflier,

Forgot to mention, but your right... This thing looks like it could let the magic smoke out at any moment!

You could get the same effect for less money if you'd buy a 1.5 or 2 terabyte drive and just set up partitions for each kind of data you want to organize. Or you could avoid  the very real possibility of guessing wrong about the size of partitions you need by keeping the mammoth drive in one partition and setting up folders for each type of data and arranging your stuff in those folders.

Time to free ourselves from those DOS era notions about how to "organize."

Granny,

Your certainly right but I happen to have 15 or 20 80-200 gig ide hard drives around already.
I also had the monster case and just figured it would be a cool box to have around.

I've also always just preferred physical drives to partitions. Yes since the dos days. Smiley

Yes your probably right, but it won't be moving from my basement much. This is no laptop!

Today, I finally got around to ordering the remainder of the parts I need.

There will be a 10 port USB hub, which I might expand to two in the future, but one for now.

Also ordered 6 more usb to ide adapters, I will have 10 of them now....

Will continue the build once parts arrive. In the meantime, I'm putting in the front panel blanks, which I still have to paint since I can't find any white ones...Also installing the floppy and I may get some castor wheels going on this beast, since yes,
It will be awfully heavy chock full of hard drives like this.
