I asked for help on vogons during the course of this build, and thought I'd write up a post about my journey. The theme here is (1) rebuild an old box I had/used and (2) use as many Intel parts as possible (I'm a former employee).

Back in March/April I decided I want to rebuild a system I had put together in 2000-2005: dual slot 2 Xeon 450mhz 2mb, 512mb ram, 4x Seagate 10k RPM drives, in an Antec (Chieftec?) beige server tower. Quickly I learned how rare the C440GX+ motherboard is now, and kicked myself hard for letting it go for nothing ~15 years go. I decided to build an L440GX setup, and maybe someday a C440GX+ would come along and I'd try to snag it. So here we go:

file.php?mode=view&id=224314

It came with 512mb RAM across 3 sticks, and a pair of 600mhz Katmai's. Cool, I always had an affinity for Katmai, that was the first PC I bought and built (I built earlier 486 class boxes from parts heading to the dumpster). Turns out the Antec case is now also very hard to find, so I opted for a modern glass Antec C8 case. The glass is nice, I enjoy sitting and looking at the components. Here's the system with my first set of hard drives, 4x200gb Intel S3700 SSDs. They're not period-correct, but they're Intel parts and were dirt cheap.

I picked up an Adaptec 2410SA RAID controller (I never had hardware RAID before, but always wanted it), which in keeping with the Intel theme has an Intel 80302 processor on it (i960 RISC architecture!). Unfortunately the Intel SSDs were too new, they were not detected by the RAID controller.

I had to swap it out with a 3ware 9500s, which worked great with the Intel SSDs, but does not have an Intel processor on it. Here's the system with the SSDs mounted for nice viewing:

The nice thing about this case is that I keep finding unintended ways to mount things like hard drives in it so that they're visible and look good.

Next I picked up an Intel SRCU32 RAID controller (with Intel 80303 processor) and a pair of 147gb Seagate Cheetahs. I was missing the authenticity and sound of spinning disks.

Now I've got so many hard drives (6) in this system, I don't know what to do with them all. So I built another system, and bought 4 more! That's a dual socket Ivy Bridge Xeon, which will make an appearance later.

Hit the attach limit, next post..

Here's the SRCU32. Note the DATA GENERAL marking on the RAM: this is one of the sticks that came with the L440GX motherboard. There was some additional BIOS addon initially present on this motherboard; apparently it came from a Data General build (cool!). Sadly I flashed the BIOS to update it to latest and clear out some POST errors I was seeing.

file.php?mode=view&id=224323

So I used the system for a while as-is: dual P3 600mhz Katmai, 256mb RAM, SCSI RAID with 256mb cache, SATA RAID with 128mb cache, 2xSeagate Cheetah 10k RPM disks, 4x Intel S3700 SSDs. I'm a programmer, so I've got FreeBSD on here (period correct version 5.5 and 6.4) and I'm having a blast sitting here coding. I've been switching off between this system and the dual Ivy Bridge system. The Ivy Bridge box is also great, but lacks the soul/character of the P3.

Fast forward to around a month ago, and I caught a C440GX+ on ebay!!!! It was mislabeled as an L440GX and came with a pair of P2 400mhz 1mb units. Under $100 shipped. It was sold as-is, so I put odds of it being functional at 50/50. Here we go, the first power on...

file.php?mode=view&id=224324

Jackpot!

I quickly ordered a pair of P3 700mhz 2mb units. These didn't quite work 🙁 The system POSTed and booted, but the second CPU had no L2 cache enabled at all. What a shame, from what I could tell, these CPUs are beasts. I was able to trade them for some 550mhz 2mb units, which are now working great. Some more fiddling, and here's how the two boxes look now, basically complete.

My tower of Xeon power!

At some point I'd like to pick up graphics and sound cards and run some old games. Anyone remember subspace?

Forgot to mention the 2gb CL2 *unbuffered* ECC RAM upgrade I bought for the P3 Xeon system I got along the way as well. Two of them were initially flaky and would not POST / pass memtest86. I pulled them, went over the contacts with a clean pencil eraser, put them back in, and now they work!

Neither the C440GX nor L440GX documentation indicate that unbuffered 512mb DIMMs will work; the claim is that registered DIMMs are required at this capacity. Happy to report these 512mb unbuffered DIMMs work fine in both motherboards.

At $100, a dual Slot-2 board is almost a no-brainer, if one is looking for that . Great builds

If it's dual it's kind of cool ... 😎

Awesome builds thank you for posting them. That mismarked motherboard and dial xeons for 100 bucks wow what a steal.

Even though I have a few period correct server cases I still much prefer putting these old dual socket systems in modern cases with better airflow.
Showing off your computer has 2 CPU's is also a benefit, especially slot cartridge CPU's!

The way you have laid everything out though is truly beautiful, bit empty compared to my fully loaded builds but way better looking.

I am jealous about your Slot 2 find, I've wanted one for over 10 years. (would help if I actively looked I suppose) but can tell it's in good hands.

It's easy to say the C440GX was a steal when you know it works 😀 I had no idea what would happen when I powered it on, it could have easily been a waste of money: no POST, melted, started on fire, etc.

It came with VRMs but no retention bracket (well, a DIY improvised one). My other hobby is woodworking, I figured I would make a proper bracket out of wood. But then I got creative and just used some string to suspend the CPUs from the top of the case. This works way better than it sounds. When the case is on its side (motherboard flat), the heat sinks make the CPUs want lean away from the normal top of the case, and the string stays taut. Of course when the tower is sitting normally/upright, the strings are carrying the load of the CPUs and heat sinks.

A downside of these modern cases is that there's no good place for CDROM or floppy drives. I just have to take the glass off and hang these out the side. I don't normally use either (actually don't even have a floppy, just CDROM), so it's not a big deal. The case does have some internal 3.5" bays, but they're not ventilated properly at all, there's no way I'd mount these Cheetah disks in there, they'd overheat. Modern SSDs are fine back there, though.

The visible areas of the cases are nice and clean, but all the cabling hidden behind the motherboard is a total mess!
