Re-sharing response from a similar question: We're working on some updates to the PCB to address feedback we have received over the years. I don’t have an ETA to share right now, but they are coming.
Worth waiting for a sale and just buying an ALT barebones. That'll get you the PCB, diffuser and you could always sell the case parts on eBay. 😂 I think the low profile was $99 during BFCM last month.
