I bought a rather cheap socket 370 board, the Canyon 6SP2AS-T. Supposedly it's Tualatin-capable, but the seller tested with a Tualeron and not a PIII-S like I've got waiting for it, so I suppose we'll see how it goes. Fallback CPU is a Coppermine 1GHz PIII, but I'm hoping it won't come to that. It's going to replace Samsur. I find even with the 512MB RAM limit the 815EP is loads more stable than the KT133A. Samsur's board needs a new BIOS EEPROM and probably a recap, so it's definitely going to ride again one day, but for now, friendship ended with Thunderbird, now Tualatin is my best friend. I may have jumped the gun a bit and already wrote out a spec list for the machine, even though the board hasn't even shipped yet and I haven't tested to see if it works with my PIII-S. I'm hoping it will. Shipping is from the Ukraine, so wish me luck on it arriving in one piece... That probably explains why I've never heard of the brand or this particular board before. It's probably more popular in Eastern Europe. From my limited experience BIOSes tend to be in English exclusively anyway bar regional computer standards like the PC98 or whatever, so that shouldn't be an issue.
A big bonus of switching platforms is that I don't have to worry about overloading my power supply or accidentally overheating the CPU now -- Tualatin sips power by comparison with Thunderbird, and the Startech cooler I was using will be more than adequate considering it's rated for up to a 1400MHz Athlon. I've already slightly de-tensioned the mounting clip so I don't have any sad times with the socket on the board to account for the heat spreader.
Plans are to use the Ti4200, drives and PSU I was already using with Samsur, and my Vortex2 I've got laying around not doing anything. A 512MB RAM ceiling is the perfect excuse to make a 98SE build with A3D. If I had a Voodoo3 or better, I'd be willing to throw it in instead, but I don't and I'm not interested in paying the 3dfx tax. Most notable Glide games run on Al-Jalima's Banshee anyway, and what doesn't already has a working D3D or OGL renderer anyway.
