Zdravo Marko, About 7 years ago I implemented something similar while at Georgia State University. I used Wyse Thin Clients (it was C90LE IIRC) and they worked like a charm. I see that Dell took over Wyse in 2012.
Right now at Carnegie Mellon University I use Intel NUC NUC5CPYH (2 cores Intel Celeron) which I got for about $140 with memory as my desktop. I had SSD drive from before. http://www.newegg.com/Product/Product.aspx?Item=N82E16856102140&cm_re=nuk-_-56-102-140-_-Product I am running full blown RedHad desktop on it because the other members of the lab use that. With exception of MATLAB which takes 2 minutes to load everything is 100% usable. We already made a decision from now on only to use NUC as desktop computers in our lab. I have tested OpenBSD on it but without X. I have another NUC unopened sitting on my desk so I will be happy to test for you over the weekend and post dmesg if you want. I know that NUC is not exactly what you asked for but for about $160-$170 here in the U.S. saving $50 and getting a "thin client" makes probably no sense. NUC is completely silent and draws about 10 - 15 W of electricity. I am not sure what is electric consumption of current Thin Clients but I would be surprised to learn that it is much lower than 10W.
