The interiors of the case are well designed. The HDD slots and 5.25″ slots are located in the front section and the power supply is located in the bottom of the case. You will find the Motherboard above it. There’s also a removeable dust filter, like in the front panel which is located under the power supply.
The back panel of the case has a slot for one 120mm fan, which is pre-installed by default. The fan, like all the three fans in the case, has a fan speed switch in the backpanel of the case. With the switch you can put the fans in either low, normal or fast mode.
The two other 120mm fans are located on top of the case meaning that you can even isntall 120mm x 240mm water cooling radiators in the P280. This is a feature which I’d like to see available in more cases in the market!
All fans are powered by a single molex connector. There are four fan connectors on top of the molex connector and four slots (one free with default fan installation) for proprietary fan controllers provided with Antec tri-speed fans.
All expansion cards are secured with thumbscrews. There are also two holes in the backpanel for external water cooling systems. We’ve seen such holes in many cases so far and if you have a external water reservoir or external water cooling system you know how handy these will be.
There are six separate hard disk trays in the P280. All of the trays support either 3.5″ or 2.5″ disks. The trays are toollessly removable.
Above the six 3.5″ trays there are places for two 2.5″ SSD:s / HDD:s. Just push the disk in to the tray and you’re good to go. No tools required.
All HDD caddies support 3.5″ disks as well as 2.5″ disks. Both disk formats are secured with four screws, tho only 3.5″ connectors have rubber dampeners attached in to them. Unfortunately the P280 did not come with enough screws for every HDD slot to be populised with 3.5″ disks.
Above the hard disks are three 5.25″ slots. 5.25″ drives are secured using tool less clip system. Just bend the lever a bit, push the drive in to the tray and release the clip. Could it get any easier?
