Hey, thanks for the help; I appreciate your offer but like you mention it does sound quite expensive. I was able to get a quote at thermaflo.com for 3 pieces, which in all would cover the panel I need. But they run for about $70 each, and I can't really justify the expense.
On a lucky take I found
these Thermalloy heatsinks :
10 of these for $9.99 US, and they measure 3" wide by .475" high by 4.75" length. So I'm thinking of getting these and putting them together.
That passive radiator you posted looks really nice; I'm surprised no one in the US is offering it. I don't like the acrylic covers because they seem to block air currents, and the fact that it interfaces with aluminum, it seems it'll be a corrosion generator. But it is quite appealing nonetheless.
I'm curious what company do you run? Is it about watercooling products?
Regards,
