Zalman 5000S:
It looks tall and rather narrow, which is a good thing because there's a lot of vertical space in my case but the CPU is right up against the PSU so there is little horizontal clearance.
In other news, I successfully installed the Thoroughbred CPU with the help of an assistant more dexterous than me to manage the clips. The old Thunderbird was bare metal on the heat sink, with almost no thermal grease left. With it gone and the Thoroughbred and the Startech cooler installed, I'm getting massive performance improvements in CPU-bound games (with the FX 5900, that's basically all of them 😁). Doom 3 was formerly utterly unplayable but now runs acceptably at high quality 1024x768, and I'm thinking of trying 1600x1200. Qbism's extremely demanding software renderer for Quake II with colored lighting now runs at a solid 70 fps at 640x480 with no significant slowdowns. I got it all the way up to 1733 MHz without the need for a wire or paint mod, which I thought was impossible. It's even (slightly) quieter now. With the use of Thermal Grizzly Aeronaut thermal paste, temperatures are down from 55 C to 38C at idle and rise only very slowly under a stress test instead of shooting up and holding at 85 C.

Whatever cable management this PC once had is now gone.
