I use them with hardware motion controls, so the latency is not so critical as for software step generation. Note that these Optiplex models come in 3 sizes. SFF is very compact, but uses a laptop-style CD reader and only one spot for hard drive. The mini-tower is a bit bigger inside and has room for a little expansion, and then there's the full-size tower, but those may be rare versions.
