There are various types of small form factor cases available in the market today. It includes mini-ITX tower cases, mini-tower cases, SFF cube cases, and slim cases. If you want the sleekest and smallest dimension case then you should look for a slim computer case or SFX case. I have written many articles about PC cases in this blog. Previously I have listed down the best mini-ITX cases, mini-tower cases, mid-tower cases, full-tower cases, cube cases, and silent cases but here I am going to list down the best slim PC cases or low-profile PC cases for building an HTPC or SFF PC for home or office use.
A slim or low profile computer case is narrower in dimension or has lesser width and can accommodate only mini-ITX or up to micro-ATX motherboards. These slim cases also have limited expansion slots and generally, you can only fit low-profile expansion cards in them whether it is a graphics card, sound card, or any other card. These small form factor cases are great for building an HTPC or a normal desktop for work or office where you have a shortage of space.
