Completely new to this

I'm looking to build my first PC as a sort of game center media hub hybrid, that will match console performance for now if not exceed it, but can be easily upgraded in the future. I don't have a lot of money and am looking at the £300-£450 price point, this is what I have come up with on PC partpicker any changes to recommend that improve performance or upgradeability for my needs at the same price or match performance at a lower price?

1) That CPU is very low power, you will not get console performance out of it.

2) Your motherboard only has 1 PCI Express slot, you can't fit the Wireless Adapter in there after the graphics card. (PCPartPicker also gives the error)

3) The cooler, that comes with the CPU, most likely already has thermal compound included, no need to buy it separately.

That case is causing all kinds of compatibility problems.

Ideally looking for a horizontal case for cinema system setup into a low TV cabinet

Can probably use an Ethernet cable if a card for that is cheaper than the WiFi one but would like the option to fit a WiFi card later

Treat me as someone who understands how to use a computer but when it comes to workings of the device is limited to about power button turns it on
