I really love the full-size layout in the office as I am an engineer and work with Excel spreadsheets and numbers a lot. But unfortunately, the full-size layout isn't very popular at all and there are not a lot of options on the market. Leopold quality is decent but I absolutely dislike Cherry blue switches.
So I found this board on eBay, thought it was a pretty rare combination (Cherry brand not Das, Black switches, blank POMs, ISO layout and BNIB condition) and decided it would be a good replacement for my office keyboard or the time being. I like linear switches like Blacks (I know there are some better linear switches on the market but still it is much better than Cherry Blue). But I was wrong

SO finally I've decided to keep my Leo but replace switches to decent linear ones but I would like to ask the community what guys do you think, is it rare keyboard because of that combination and it is maybe worth to keep as a collector's item? Or maybe there is nothing special in it, ISO layout is unpopular etc. Any advice would be very welcomed

P.S. Sorry for the small stain at the top right corner, I didn't notice it when was taking pics but already removed it with a wet cloth.
