I would rather go for socket 370 than slot 1, as it is easier to come up with a silent / nearly silent cooling solution for S370 CPUs.
Slot 1 CPU coolers are usually just good enough, you are limited to loud 40/50mm fan(s) and you could end up having clearance issues with memory, caps, etc.
I have a MSI MS-6163 Pro, PIII 650MHz cooled passively and temps are great, but it was a real pain to find the right heatsink and it almost touches the memory modules.
And in terms of slot 1 coppermines, google is you friend.

Well i found one slocket adapter , i guess that for coppermine there is not anything compatibility-wise to look for on those adapters?
Don't be too sure of that. There are three different So370 socket pinouts:
PPGA (Celeron Mendocino only)
FC-PGA (Coppermine only)
FC-PGA2 (Tualatin only)
Generally (but not always) the sockets tend to be backwards compatible, but they are never forwards compatible. So if you get a PPGA-slocket adapter, you can't run Coppermine CPUs in it.
I can't find any clear specs on this "370SP rev 2.0" adapter, but the 1.0 was definitely PPGA only. Of course PPGA can be modded to FC-PGA with patience, some soldering skills and the relevant pinouts, but I'd double-check this before shelling out on it.
And for slot1 mobos, i know that the 440bx is the top notch , but any other chipset that i should look for?
Edit: i found a Soyo Sy 7vba133 with a pentium 3 1.0ghz, should i get it or should i get a Asus P3B-F ?
Depends what you want. The i440BX gives you the lowest latencies and higher performance at a given clock, but by 2000 it was dated and lacks a few important things:
- no 133MHz FSB support. It generally does overclock well, frequently up to 133MHz and beyond, but then you hit the next issue:
- no 1/2 AGP divider support. So if you overclock the FSB to 133MHz, you're running the AGP port at 87MHz. Not all AGP cards respond well to that.
- 1/4 PCI divider support was rare. Same problem there, PCI devices (particularly HDD controllers) tend not to like higher clock speeds. If you want to try to run 133MHz FSB on an i440BX, you need a board with this divider. Note that this is the sort of thing which can and does differ between revisions.
- max 128Mb memory density. That means max RAM of 1GB (if you have four slots), and that only works with 256MB double-sided modules with 16 16Mx8 chips each. Most PC133 modules you come across will be single-sided modules with 32Mx8 chips (or appalling 16 chip single sided monstrosities with 32Mx4 chips, which are not supported by Intel memory controllers in any case). Note that "single sided" and "double sided" refer to the internal organisation of the chips, it is entirely possible DIMM with chips physically only on one side is double-sided (8 8Mx16 chips), or with chips physically on both sides is single-sided (16 32Mx4 chips). If you don't want to worry about this, stick to 128MB DIMMs with no more than 8 chips. Or choose a more modern chipset.
- no ATA-66 or 100 support on chipset. Less of an issue, as you're probably going to use a SATA card anyway... (and if you want a period HDD, the HDD itself is going to be the bottleneck at ATA-33 speeds)
To avoid these issues, you could look for a board with the Via ApolloPro133A (694x) chipset. It gives you:
- 133MHz FSB support
- 1/2 AGP divider
- 1/4 PCI divider
- max 256Mb memory density and support for x4 chips, and max 2GB total RAM.
Downsides:
- worse performance at same clock (although just a few percent)
- the 686A/B southbridges are notorious for PCI compatibility issues with Creative sound cards (although in Via's defence, Creative used proprietary Intel-only extensions to the PCI standard where Via stuck to regular standards)
Or if you're lucky, you might find a board with an SiS635 chipset. These things were rare even in the day, but offered clock-for-clock performance equal to the venerable i440BX, no significant compatibility issues, yet the whole feature set of the ApolloPro133A.
Avoid Intel i815-based boards, if only because of their 512MB memory limit. And the less said about i820-based Rambus platforms the better 😉
