THE CORE X9 INTERIOR
The interior of the Core X9 is so spacious that even the 900D would have a hard time competing.
All three removable 5.25" drive bays feature tool-free lock mechanisms.
The mainboard tray has three rubber grommets for cable management and a large opening beneath the CPU care (it's taken however by another plate).
Right beneath the mainboard tray we see two drive cages each with three drive trays.
These drive trays are quite sturdy and can open on both sides to make it easier to mount the drive (support both 3.5/2.5" drives).
Both drive cages are removable and so are the fan/radiator mounts placed right beneath them (you can mount these on the sides of the case).
This is what the interior of the Core X9 looks from the right side (do notice the two rubber grommets next to the PSU area - that piece is also removable).
Once again both the right side and the top panels feature removable air-filters (magnetic ones).
Depending on the size of the PSU you choose to mount the base has room for 120/140mm fans and up to 480mm radiators.
There's also a metal stand at the rear end which you will need to adjust according to the length of the PSU.
Remember the mainboard cut-out beneath the CPU area?
Well after removing the mainboard tray and turning it over we see that it's actually yet another 3.5" drive mount (you can also use it with two 2.5" drives).
