Now for another project box that you haven't been told about yet -- I have a nearly mint IBM T42. Dothan core Pentium M @ 1.7GHz, mobility Radeon 9600 64MB, 2GB DDR-333. I'm currently imaging the 128GB SSD I originally put in it over to a 256 and expanding the partition. There's not even any slack in the hinges, the rubberized coating on the lid hasn't returned to the primordial ooze all these coatings eventually do yet... I really like this thing, even as much as it tries to make me hate it. I've swapped the CMOS and running batteries, and it's good for about two and half hours, which for generic cells on a twenty year old laptop, isn't bad.
The CPU is middling but not slow enough for me to try to track down a Pentium M 765, which at 2.1GHz is the apex of what this machine can take, as it can't take the later 533 bus Pentium M chips that are more common. The DDR-333 is an artifact of the chipset -- it's even stuck in single channel for the same reason. The T43 fixes this, but its video is PCIe based instead of AGP, so one can't run Windows 9x on a T43 very easily like they can the T42. Not that that's especially relevant for me, as it's running XP SP3.
The video is the mobility Radeon 9600 as mentioned, and honestly, I kind of wish I had the 9000 instead. It'd have the same amount of VRAM, be about as fast in general use, and be much less inclined to do early BGA shenanigans and desolder itself from the board for getting too hot. The 64 meg 9600 I believe is on a 32-bit memory bus too, so it's really not as good a performer as it initially sounds. I can't run pretty much any game at the panel's native 1400x1050 resolution, another thing I wish it didn't have -- the 1050p panel is 50Hz, and is right at the cusp of being inscrutable to my eyes without any scaling. Since swapping the screen is so relatively easy on this model I may yet track down a 1024x768 LCD that'd be more appropriate.
I upgraded the WLAN card from the original Intel 2200BG to a TP-Link card based on the Atheros 5416 (that, under Windows XP, claims to instead be an Atheros 5008 for some reason). I gained real WPA2 support and wireless N, so it wasn't for nothing by any means. The annoying part was that I didn't know the 1802 error I was expecting for using a non-whitelisted card would prevent me from even entering the BIOS, much less booting, so the no-1802 utility had to be run without the WLAN card in at all. That was a re-disassembly full of annoyance and swearing.
I just had to replace the entire CPU cooler because the original has the fan riveted to the heatsink, and the bearing isn't accessible, so when the fan finally started buzzing loudly, I had to swap the whole stupid thing. 20 screws to get the keyboard and palmrest out by the way, and another 4 to get the screen hinges out. How did we ever classify these as being easy to service? I guess everything else must have just been significantly worse.
I was pleasantly surprised that it seems to have gigabit ethernet provided by an Intel chip, a nice bonus for a laptop but I suppose an expected one given the price point this was at and the market segment it targetted. Even cooler is the fact that it has a PXE boot ROM, so I didn't have to write a CD just to boot into GParted to clone my drive and expand the partition, just had to use the PXE server I already keep running locally. And it'll natively boot from USB, too, which isn't amazingly common on machines of that time. If you'll recall, I originally set up the PXE server to get my Latitude C400 to boot from USB using the Plop bootloader as it didn't have an optical drive or floppy.
