I picked up a P133 system on Craigslist for $20. It was nothing special :

AT Case, PCChips M572 Motherboard (Intel 430TX chipset), Pentium 133 CPU, 40GB IDE hard drive, 128MB SDRAM, ATI Rage XL 8MB PCI graphics graphics, and Sound Blaster AudioDrive PCI sound card

I was planning on a parting it out and using the case for another retro build, then it dawned on me that this motherboard can be flashed with a patched BIOS to support a K6-3+ CPU. I had all the parts laying around so this is what is in it now:

AMD K6-3+ CPU @500MHz (83.3MHzx6), 256MB SDRAM, 80GB IDE hard drive, 3dfx Voodoo3 2000 PCI graphics card, Sound Blaster 16 ISA sound card, Intel Pro/1000 PCI network card, & Logictech Wingman gamepad.

The only issue I had is that I could not get any Compact Flash or SSD to work while running the FSB at 83.3MHz. If it were not for the patched BIOS, I don't think I would have even bothered trying do anything with this motherboard, but in this case I am glad that I did.

I've a very similar setup with an Asus TXP4. I've had better luck with the SSD though - using a Promise IDE controller with a PATA to SATA adapter, I've had no problem using a Team Group 120 gig SSD. Have you benchmarked with the motherboard cache enabled and disabled? I found that my 3D Mark 99, 2000 and 2001 scores were higher when the L3 cache was disabled, presumably because I too had 256 megs which exceeds the TX chipset's cacheable limit of 64 megabytes.

I only have a couple StarTech IDE to SATA adapters and may have better luck with a different brand. Most of the benchmarks don't show much of a difference with the motherboard cache off vs on. If there is a difference, it is not much.

That's exactly the adapter I'm using in this box.
No, the difference isn't huge; my 3D Mark 2001 score is 1,749 with the L3 cache enabled, 1,948 with it disabled.

That is a good purchase considering many would have sold it as a "vintage" computer via fleabay for 5X+ that amount plus shipping

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

I agree . I had a PC Chips M550 430TX based board back in the day . It worked fine . Hopefully the M572 is just as good if not better .

I tried a different Compact Flash to IDE adapter and so far it is working. Keeping my fingers crossed I won't have any data corruption issues and will keep plenty of good backups!
