A year ago I was working for a company that used such PC in the cloud services. 10 months of renting that cost about the same as buying an equivalent laptop. It wasn't good.

If you mostly need a machine for word-processing and do something intense for an hour a week there might be a possibility of saving money, but for regular use no way.

Also if you have an office where people occasionally need a powerful system then just buy one powerful PC and have them share.
