I managed to use this Antec case for the Intel PR440FX build with dual Pentium II 333 MHz Overdrive units. It turns out that many cases, although not full E-ATX, can support these half E-ATX motherboards, like the PR440FX. My Opteron 185 socket 939 system had such a case, so I swapped cases around.
I took some photos to demonstrate what I mean by "half-EATX".
This motherboard uses a very early and peculiar ATX I/O shield. Although the motherboard came with an I/O shield, it doesn't snap into an ATX motherboard's I/O shield form factor. It mostly fits, but there are some gaps around the edges. So I took a regular ATX I/O shield and cut away the centre guts, but left a little flap on the right side to cover the gap. I also had to cut out part of the ATX I/O shield's frame to fit the game port's screw. The whole hack isn't as elegant as I'd like so I'll likely revisit this in the future.
The motherboard has an onboard AIC-7880 SCSI controller.. The manual states that it can burst up to 40 MB/s, however I thought this card could only go up to 20 MB/s ? Unfortunately, the only quiet unused 68/80-pin SCSI HDD I have is a 15K U320 36GB unit. It is way overkill for this controller. I typically use that drive for benchmarking various SCSI controllers.
The motherboard contains a Crystal CS4236 audio chip. Is this sound card any good? I wasn't sure if I should fill the ISA slot with another sound card.
The motherboard contains this wavetable header. Is there a converter cable which lets me connect this to a Dreamblaster S2 or X2?
Lastly, I am faced with the selection of graphics cards for the system. I have already filled two PCI slots with a gigabit ethernet card and a USB 2.0 card. Looking through my bin of unused PCI graphics cards, I have:
FX600 256 GB (currently in an Intel SAI2 dual Tualatin I plan on decomissioning)
eVGA GF6200 DDR2 256 MB
eVGA GF6200 DDR2 512 MB (vga port doesn't work. DVI port works)
BFG GF6200 DDR2 256 MB
GF2 MX400 (a slowed down discount POS, my good GF2 is in the Proserva dual P233mmx)
Matrox Parhelia 512 (probably won't work)
Matrox Mystique 220
Permedia2 based on P4020GFN
What do you think best suited for the system, assuming it was your system? I was thinking the 3DLabs Velocity would be fitting as it is a workstation card, but its 3D performance for games it lousy. Same for the Permedia2. The FX600 is tempting for a graphics overkill type of build, plus it is a workstation card. The spare GF2 I have is really a budget piece of junk and would sort of damage the high-end nature of the build. I think the Riva128 is a bit underpowered for a PII-333. Thus I am thinking either the TNT2 M64, G450, or Velocity. Undecided, I put the G450 in the case.
