Solas is a clockport device that adds addressable RGB LED strip support and a number of other features to a clockport-equipped Amiga. It started out as a simple adaptor to add LED strips to the inside of an A1200 case using power from the floppy power header, but has suffered perhaps the largest case of feature creep I've ever experienced, now using the clockport to allow software control of the LED strips and a host of other features. It's still in development, but coming along nicely.
The Solas board is designed to fit directly on the clockport on an A1200, and will fit around the ROM sockets and over the chip RAM / RTC area. It should fit with an Indivision, but it won't fit with a FastATA or a Mediator. But that should be okay, because the board can be fitted with a male clockport header instead and mounted elsewhere, connecting to the motherboard via a cable. This means it can be used in Mediator tower setups, and other Amiga models with clockports.

Current Feature List
Solas has grown from a simple floppy power adaptor into a fully-fledged, addressable RGB LED controller. Currently the feature list looks like this:
Fits directly on A1200 motherboard clockport header
Option to attach by a cable instead for Mediator users or other cases where accessibility or mechanical compatibility dictates
Supports use on clockport splitters, Zorro card clockports etc.
Addressable RGB LED strip support
Support for one or two strips of 5V addressable LED strips (sometimes known as 5VDG or D-RGB strips), commonly found in gamer PC cases and under names like ASUS Aura, MSI Mystic Light Sync...
Up to 100 RGB LEDs are supported on each strip, though limitations on power supply, update frequency etc. will apply
Software control of individual LED colours, presettable light patterns can be configured via software
Configurable LED Responses
Independent LED profiles can be set to respond to different events
Responds to Amiga's audio output (e.g. VU meter or pulsing effects)
Responds to hard drive, floppy and PCMCIA activity LEDs
Fan Speed Controller
Variable voltage fan speed controller to allow speed control of most standard fans
Speed can be controlled via software or by the Solas board based on a temperature sensor
Automatic fan speed control implemented as a PID controller for smooth operation with minimum noise
Supports both 5V and 12V fans, one of each can be used simultaneously
Up to three temperature sensors can be added - two LM-35 type digital sensors and one thermistor type sensor
Software readable via the clockport
Software calibration adjustments to allow for different sensors
Option to control the fan speed based on the input from any of the sensors
