BUILDING THE SYSTEM
As always the purpose of this section is not to build a fully working system but rather to showcase what you can expect from the case at hand in terms of interior space.
Since Antec classifies the P280 as a Super Mid Tower it may not be as large as some of the other HPTX/XL-ATX compatible Full Towers out there but still its interior is a lot larger than that of a normal midi tower.
You can mount even the largest CPU Cooler out there without worrying about clearance issues, at least not related to the case itself.
The Performance One P280 also has room for up to 330mm long graphics cards.
Unlike other similar PC Cases you will not forsake the bottom routing hole if you decide to use a long power supply such as the Huntkey X7 we used in this review.
