Gigabyte BRIX S GB-BXi5H-5200 Review http://www.bit-tech.net/hardware/2015/03/23/gigabyte-brix-s-gb-bxi5h-5200-review/1
I use these at my office, and equip them with 16GB RAM and a 256GB mSATA SSD. Performance is great in this respect and they look the part sat on the desk. I also use the bigger cousins (with the 2.5inch HDD space) with 2 x 1TB SSD's as a database backup with the i7. All in all, I wouldn't use this as a personal computer but it's performance is more than good enough for day to day tasks, and as a small portable server!
