Thin Client Sample Hardware
I found an advertisement on thin clients and decided I couldn't beat the price (small business ditched their Citrix implementation)…
Being creative with the hardware, I installed pfSense. With proper specs, thin clients are excellent choices.
I removed that picture since it was basically making your post a spam post. If you want to list the model you used and link to the source, that's fine, but try not to turn the post into one large ad for another company.
There are quite a few others that have used thin clients for pfSense before. They can be very good, provided you can stuff an extra NIC or two in them (or use VLANs)
