An ebay listing for a 9U open frame 4 post server rack with caster wheels. It's around $200, and the picture shows a racked 2U network switch inside of the server rack. There are dimensions listed on each side, showing a 19.7" height , 19.7" width, and a 21.7" depth - perfect for some standard 20x20 HVAC air filters and the box fan needed to turn it into a Corsi-Rosenthal Box.

Grainy screenshot of a survey: "How likely are you to recommend this air purifier to a friend or colleague? Answer: 1, not at all likely. Please explain why you gave this score: I need you to understand that people don't have conversations where they randomly recommended air purifiers to one another." Corsi Rosenthal box users: bombastic side eye. (Depicted with monkey puppet side eye meme.)

#AltText: photo of a boxy chandelier, faced with fans that are glowing cyan and teal, with splashes of neon-hued magenta, purple, blue, green and yellow. The fans have subtle diagonal braces and hexagonal enclosures which enhance the pronounced vapourwave aesthetic, which could be from 1987 or 2027.

On closer inspection, it can be recognized as a fancy Corsi-Rosenthal Box.

The future is now!

I honestly forgot these filters were white. πŸ˜‚

CR Box, looking at a 20x20x1 3M MERV-13 filter. There are black PC fans on top. The date it was constructed and put into use ("2/18/24", so it is roughly 10 months old) is written on it.

The filter material (folded into pleats) are a dark grey, almost black. There's also wads of cat hair all over the pleats.Another same/similar CR box, with a 20x20x1 (MERV-12) 3M filter, and the black PC fans on top. The date on this one reads "12/6/24" (so only a few days old). The filter material is nice and white, looking clean and new.

Hey PC fan #crbox community, I'm noticing a very faint burnt smell from upward facing fans only on my two boxes built with Arctic P14s. If the room is closed the odour becomes noticable. A close up sniff reveals the sideways fans are fine.

@thetyee I see that C-R box in the background!

Good to know that the Tyee office is following the science, as you've sometimes reported on.

Best wishes that you each stay physically and cognitively healthy, and that your ongoing efforts for excellent reporting are never impeded by long covid.
