Choosing between a custom-built and prebuilt gaming PC can be tricky. At UK Gaming Computers, we offer both options. In this article we'll break down costs, performance, upgrade potential and convenience, helping you make an informed decision when purchasing your next Gaming PC.
1 - BUDGET
Prebuilt Gaming PCs - Best for a Fixed Budget
- Lower upfront cost - We optimise prebuilt PCs for value, using smart component pairings that we buy in bulk so get great deals on. Most of our Next Day PCs can be bought from us at the same price you'd pay if you built your new PC yourself.
- No hidden extras - Includes an Operating System & Wireless Card.

2 - UPGRADABILITY
Prebuilt Gaming PCs - Limited but Possible
- What can you Upgrade?
- GPU - If the PSU and Case size support it
- RAM - If extra slots are available, else you'll have to replace the current sticks too
- Storage - Extra NVMEs, SSDs or HDDs, if the Motherboard and Case allow
- CPU - More difficult, but anything compatible with the Motherboard
All of our Prebuilt Systems come with standard ATX cases & PSUs, with no proprietary components. This makes future upgrades much simpler.
Custom Built PCs - Full Upgrade Potential
- What can you Upgrade?
- Everything! - No limitations here, we use higher wattage PSUs and larger cases to cater for larger GPUs, additional storage, upgraded cooling & more.
When designing the base spec of our Custom Built PCs, we make sure to overspec the components with upgradability in mind, this leaves the door open to customise to your heart's content whilst speccing up the PC before ordering, and with future upgrades.

How soon do you need it?
Prebuilt Gaming PCs - On the shelf, ready to ship
