PC Build Improvements? (First Build)

[ARandomUsername]

Hi, just wondering if there is anything I should change/adjust on this PC or any improvements to be made? (e.g different version of GPU, cheaper/better SSD) Thanks for any help.

https://uk.pcpartpicker.com/list/W4fYWD
CPU: i5 8400
GPU : GTX 1060 6GB (Palit Jetstream)
MB: MSI H310M (Micro ATX)
HDD: Barracuda 1TB (Seagate)
SSD: Kingston A400 120GB
RAM: Team Vulcan 2x8 2400 Mhz DDR4
PSU: CX450 (Corsair)
Case: CiT Blaze - Isn't on partpicker, but I think it is still compatible. Please say if it isn't
OS: Win 10

This is my first time building so any tips for that is helpful as well! Thanks!
P.S Budget is around £750, but honestly lower is better whenever possible.

A 120GB SSD is too small. Windows updates and the other things that require installation to C: eat up that space. Get a 240GB SSD.

Have you got any recommendations for a good value 240GB SSD?

The MX500 SSDs get the "Best Cheap" mark -- https://www.tomshardware.com/reviews/best-ssds,3891.html
