Amazon has a "refurbished" program, where you can find lots of cheap thin clients and smaller form factor desktop machines.
However, the refurbished computers often have their SSD/HDD replaced with a crappy one that is unreliable, so I would recommend assuming that you assume that you will need to buy storage in addition to that.
But, overall I really like Amazon Refurbished because you get a better quality guarantee (warranty/returns), but a cheaper price.
Eventually? How about now?
