Is this good for gaming?

Only for light or older titles. It relies on Intel integrated graphics, so demanding games will run poorly. A discrete graphics card would be needed for serious gaming.

Can I upgrade the RAM or storage later?

The tower case makes opening it straightforward, and there is a 1 TB SSD plus 32 GB of DDR5 installed. The listed 32 GB maximum means you should confirm the board's slot count and ceiling before planning a memory upgrade.

Does it come with a monitor and keyboard?

No. It is the tower only, so you need to supply a monitor, keyboard and mouse.

Why is there no Bluetooth?

The listing specifies no Bluetooth. For wireless mice, keyboards or headphones, use a USB Bluetooth adapter or choose peripherals with their own dongles.

Is Windows 11 Pro worth it over Home?

Pro adds BitLocker encryption, Remote Desktop hosting and domain join. That matters for business use; home users may not notice the difference.

How does it compare with a Core Ultra 7 desktop?

The Ultra 5 235 has 14 cores and is fine for office work and light creative tasks. An Ultra 7 model costs more and gives extra performance for heavy video editing or compiling.
