If you aren't familiar with SFFTime's U-ITX case, check it out here: https://smallformfactor.net/forum/t...ight-console-case-that-fits-3slot-gpus.18563/
I was posting sporadically in the discussion but figured it was time to consolidate updates into a single build post since I cleaned up the cable positioning and have it in a working state
The U-ITX in one of its unofficial configurations can fit a full sized ATX motherboard. That coupled with some nostalgic systems I've kept from 20+ years ago led me to work on this build.
Specs:
MSI K7T Turbo2 (Socket A/462 VIAKT133A based)
Athlon XP 1900+
Athlon XP stock cooler with replaced 60x60x10mm fan (4k rpm Sunon)
512MB PC133 SDRAM (256+2x128)
Matrox Mystique 2MB PCI
Intel 82557 10/100 PCI
Samsung 128GB PM810 with SATA->IDE 40p adapter, powered by SATA 7p-> 4p USB 5v cable
Quirks and notes of interest:
The motherboard was modded to enable its ISA slot (ref ), but I'm currently unable to use it in this case configuration.
The motherboard is interesting in that it's a narrow ATX form factor (full length, but less wide than normal ATX/M-ATX, 305mm x 210mm instead of 305 x 244mm). It's also what led me to believe it would fit well with a FlexATX PSU turned sideways (80mm+210mm < the case 305mm)
The system uses a FlexATX PSU which is not an official configuration (@PVC might appreciate that it's a Delta DPS-350AB-12
) . You can see in the 4th picture that it is mounted using one of the SFX mounting positions and the other side is secured with a silicon washer under a metal washer and an M3 screw that I cut to length to reach the stand offs.
I'm using a 24p ATX short extension which I de-pinned and re-pinned to a 20p ATX connector. I also repurposed/depinned an EPS12v/CPU 8p extension to get the 4p.
Originally I wanted to fit an Intel VS440FX with Pentium Pro 200. While it does fit the PSU would hover slightly over the motherboard
Sourcing the right PCI riser(s) is/was a challenge. I'm making the one I currently have (https://www.ebay.com/itm/256719772426) work by rigging the PCI cards upside down.
I also found that the riser I had produced IRQ conflicts but only with certain PCI cards (I wanted to use an Intel 82559 card that had a PXE bootrom available). The same upside-down setup should work if I decide to put the 440FX/PPro system back in the case.
Next steps:
I ordered 2 standalone PCI risers with a longer ribbon cable (https://www.ebay.com/itm/145134686173). that should fit. If not, I may try to use one of them just to extend the dual port riser so I can put the cards back rightside-up.
Also going to order a black slot cover so it will look slightly more pleasing. The third slot unfortunately is unusable, as you can see the motherboard's actual expansion slots block it.
Wishlist:
-an AGP riser. I have a Voodoo 5 5500 64MB AGP card that could fit with the flex PSU mounted up top. But these are even more rare and probably more fickle than any PCI riser. I may look for a fancier PCI card instead like a final generation Matrox Millennium G450.
-a custom ISA riser. It would need to make some serious 90 degree turns and I would have to give up the NIC slot. But I have an AWE64 Gold with 28MB expansion intended for the slot.
-a low profile PCI ethernet adapter with "dongle" to relocate the RJ45 jack to the rear IO panel. I think this one will work if I cut an RJ45 extension and solder it to the pins (https://www.ebay.com/itm/324460497659 plus https://www.ebay.com/itm/387398705510)
