With the side panel off you’ll find the 450D has a huge cut-out at the back, this will help with installing/changing your CPU cooler without removing the motherboard. Cable routing options are great thanks to a few small cut-outs hiding above the motherboard tray, as well as four large rubber grommets around the motherboard mounting area and an open back design behind the hard drive bays.
In the base you’ll find plenty of room for an ATX PSU and a 120/140mm fan, of course you could sacrifice the cooling space for a longer PSU, or remove the hard drive bays to make room for two 120/140mm fans or a radiator of up to 280mm.
The front fans are mounted to give unobstructed airflow to the GPU and the lower fan will help cool your storage. There is plenty of clearance on all sides so you can easily install an up to 280mm radiator in the front, all you have to do is take out a couple of screws to remove the hard drive bays.
The hard drive bays are tool free trays for 3.5″ drives, or you can screw in a 2.5″ drive to each tray. You can also buy another one of these bays which screws into the two holes on the top of this bay, giving you six trays in total.
The rear 120mm fan comes fitted with a standard 3-pin power cable and again there is lots of clearance above and below it to allow room for a radiator without conflicting with your other components.
Around the back you’ll find around 20mm of clearance for cable routing, as well as a few cable tie down loops to help keep things neat and tidy.
There are two each access 2.5″ drive mounts, perfect for those who plan on stripping out the front bays to make room for water cooling, but also a great way of expanding the total number of available storage bays.
Towards the front panel you’ll also find some extra cable routing holes that are ideal for routing fan cables to the front of the chassis.
