I don't have any pictures to show at the moment, but I've had an ongoing Quicksilver project since last summer.
It started out as a single 800mhz Quicksilver 2002 and was pretty much the basic model. It had a 40gb HDD(with Panther installed) and a Radeon 7500 Graphics card. About the only upgrade was a 250mb ZIP drive.
I pretty much immediately upgraded it to a 160gb and 120gb hard drive, and triple-booted Tiger, Leopard, and OS 9. I maxed the RAM, upgraded the graphics card to a GEForce 4MX, added a Motorola WPCI810G Wireless card(Airport Extreme Compatible), added a combo USB 2.0/FW400 card, and a SCSI card to interface with my slide scanner. All of these were transplanted from the DA G4 that the Quicksilver replaced. Probably the biggest upgrade to this computer was changing the single 800mhz out for a dual 1ghz. Unfortunately, I never got the L3 cache to work, as it seems as though Apple disabled the ability for the logic board to recognize it on computers that originally didn't ship with it.
I went through a bit of a revolving door of video cards with this system. Initially, I swapped the GEForce4 MX for a Radeon 9000, but went back to the GEForce because I didn't see any performance improvement and the GEForce seemed better behaved in OS 9. For a while, my "dream card" for this system was a GEForce 4 Ti. The first one I bought on Ebay was DOA. The second one died after about a week of use. Both times, I went back to the GEForce 4MX. Finally, I went to the Radeon 9600XT, which kills any OS 9 compatibility but is much better under OS X.
Somewhere along the way, I also changed out the SCSI card. My original Adaptec card had a DB-25 connector. I changed it out for one with a 50 pin min Centronics connector(I got the appropriate mini-Centronics to Centronics cable also-both out of the dumpster) primarily because the second card had also had an internal 50 pin connector that I've used on a few occasions(it's not in continuous use-mostly just for occasionally pulling data off or otherwise manipulating an old 50 pin drive).
Finally, I replaced the entire computer with a factory dual 1ghz, which did give me the L3 Cache. I moved most of the interface cards over, but took the chance to migrate the OSs over to an almost new 500gb WD Caviar Blue, and stuck in a refurbished 160gb WD drive for overflow storage. Interestingly enough, this particular Quicksilver was ordered(from the factory) with the exact same SCSI card as I'd been using, so I just plugged my scanner into it and went from there. I'm debating about whether or not to transfer the ZIP drive over-I rarely use it, but am glad when I have it.
This is probably my most extensively modified Mac, at least at this point.
A few others:
1. I took a 400mhz B&W G3, and installed a 450mhz G4 processor in it as well as a Radeon 9200 that another member here sold me. I ended up installing a cooling fan on the heatsink, and it's now running cool enough that I'm considering overclocking it a little bit(maybe to 500mhz or so).
2. The 400mhz G3 processor liberated from the above made its way into a beige G3 desktop. Thanks to the 66mhz bus of the beige G3s, it's actually currently running at 396mhz and not 400. If I can shoehorn a CPU fan in, I might attempt a slight overclock with this one also(again, nothing dramatic). This computer has a Rage 128 graphics card(mostly for the direct VGA output, but also better performance than the onboard graphics), a USB 2.0 card, and a Firewire card. It's exclusively an OS 9 machine, although I might still stick a better graphics card in it if I find another 9200 for a reasonable price.
Most of my other Macs have had hard drives, optical drives, video cards and RAM changed/upgraded, but I don't put this in the category of doing any dramatic mods. Both my Cubes have had base fans installed.
I'm also getting ready to start on a big project-time permitting. Erik's old and much-hated GigaDesigns 1.8 dual should be here tomorrow. I've gone through my parts box and have put together a Quicksilver(it was missing the logic board and a few other odds and ends) and the 1.8 Dual is going in that(there's currently no processor in it, although I can probably come up with one to install for long enough just to make sure all is okay before installing the upgrade). The case isn't great cosmetically, so I won't feel bad if I end up chopping holes in it for more fans. I'll probably start another thread for that project.
