I bought the case as an enclosure for an external gpu project, to protect my graphics card (and my exp gdc) from dust. The case conveniently came with a power supply, so I didn't have to buy one separately.
My 11 year old laptop that I've plugged it into is now hypercharged and it worked out many hundreds of pounds cheaper than buying an egpu - or even replacing my laptop!
Thanks CCL for a great product!
