It will take a board up to 10 x 10 inches.  The case outside is 15 x 13 x 4 inches.  Front is longest side.

250W PSU included (as originally supplied with the case).

Some scratches as pictured.  Remains of security sticker on bottom.

Slimline case ie low profile cards required.

Supplied with the original clip on feet x 4 for when used as a tower rather than as a desktop.

The pricing reflects that there are the two components;  the case and the PSU.  I will list separately at £15 for the case and £15 for the PSU if asked.
