Upgrade m15 , Hard Drive Chassi Space

Hello,

 

I bought my m15 last year with the below specification

8th Generation Intel Core i7-8750H (6-Core, 9MB Cache, up to 4.1GHz w/ Turbo Boost)

15.6" FHD (1920 x 1080) 60Hz IPS,

256GB PCIe M.2 SSD 

180 Watt AC Adapter

90 WHr, 6-Cell Battery (integrated) 

Intel(R) Core(TM) i7 Processor 

NVIDIA(R) GeForce(R) GTX 1060 with 6GB GDDR5

Killer 1550 Wireless driver

Killer 1550 802.11ac 2x2 WiFi and Bluetooth 5.0 

Alienware AlienFX mSeries Keyboard with Alphanumeric Keys - US/International 

 No Media

 

I would like to upgrade it by getting an HDD of 500gb or 1000GB.

I wasnt sure though if there is enough space in the chassis as i got the 90 WHr, 6-Cell Battery 

 

Regards

Kostas
