Why custom pcs give you more value for money

From gaming PCs to high-powered workstations - here are the 4 reasons why building your own custom PC is the way to go.


Buying an off-the-shelf computer is often expensive, especially if you need something more powerful than a standard, light use PC. Once you start adding on graphics cards and high-end processors, the bill starts to rack up quite quickly as big companies charge a huge premium for these.

Here at MCC, we often get asked if we can build a computer to match the specification of a PC from a big computer company. Of course we can, and we guarantee it'll be cheaper. Here is an example: A customer sent me the spec of a gaming PC that was retailing for £999. When we looked at the components, we were pretty shocked by the price. We could build the same system for just £650. This just demonstrates the mark up that big companie add to their PCs. The customer decided to go ahead with us, but to see what we could build for the same £999 budget. The gaming PC we eventually built was vastly superior to the original. Out of curiosity, we checked what our system would cost if bought from the big company: £1700!

Bottom line, if you want the most value for money, build your own computer. If you don't know how, come and speak to us.


A huge benefit of building a custom PC is the ability to future-proof your system. By planning ahead, you can make sure you have components included that allow for easy upgrades.

This can't be said for off-the-shelf computers. mainstream machines quite often come with the cheapest components possible in order to maximise their profits. Take the humble motherboard, for example. Pre-built systems will use bog standard parts with very little upgrading capacity. Want more RAM to speed your system up? Nope you can't, not without replacing the motherboard too, as it will already be running the maximum RAM it can handle.

As technology never stands still, and PC games get more and more demanding, it's a good idea to keep this in mind. Better to spend some money on upgrades in a few years rather than having to buy a whole new system.


Pre-built systems can be fairly drab, grey boxes. Building a custom PC gives you total control over the design aesthetics of your system.

There are so many options to choose from, including cases, RAM, graphics cards, cpu coolers and fans. There is also the option to add RGB elements into your build, if you so choose.

If you really want to go all out, you can even create a custom water cooling loop, which really adds the wow factor to and gaming PC.


We've already mentioned motherboards, but that's not the only thing that mainstream manufacturers will scrimp on. Here are some (not all) ways they will try and make more money out of you:

Power Supply Unit (PSU) - your PSU, as the name suggests, is what provides power to the various components within your PC. They are a crucial part of your build. Firstly you have to make sure your PSU is able to provide enough wattage. Pre-built systems often include a PSU that is the absolute minimum required. This keeps their costs down, but would prevent any future upgrades to, say, a more powerful graphics card.

They also tend to be inefficient. At minimum your PSU should be 80+ Bronze rated (more on that here). This also makes them more expensive and, therefore, less likely to be seen in a pre-built system.

Storage - Both hard disk drives (HDD) and solid state drives (SDD) are areas that companies like to penny pinch. For HDD's, the area to watch out for is the speed (measured in RPM, or how many rotation per minute the disk is capable of spinning). 7200rpm should be the minimum, but you will often see slower drives, which would significantly slow down your computer, especially if the HDD is also used as your boot drive. For SSD's, pre-built tend to include really low capacity drives (if they include one at all). A SSD can run up to 100x faster than a HDD, but they are more expensive per GB. A low capacity SSD is ok for a boot drive, but won't allow for storage of many AAA games, meaning load times will be noticeable longer.

RAM - Firstly, any new system should be running at least DDR4 RAM. DDR5 is now also available, but it is still fairly new, comes at a premium, and there are a few bugs to be ironed out. I'm still surprised by how many systems still come with DDR3. What's the difference, I hear you ask? There are a few, but most important is speed of data transfer (rated in mhz) . This increases the performance of your system, by allowing the data to be stored within the RAM, and eventually re-read, faster. As a benchmark, you should be aiming for at least 3000mhz for Intel systems and 3200mhz for AMD's Ryzen CPU's. The latest Ryzen processor will use DDR5 memory only, and recommend speeds of at least 6000mhz.

You also need to factor in the RAM capacity. 8GB is common, but most AAA games today need 16GB to run smoothly.

CPU Cooling - planning on doing some overclocking of your CPU? Forget about it with most pre-built system coolers. They are cheap and they just aren't going to draw enough heat away from your processor. Building a custom PC allows you much greater flexibility. From air coolers with better heat sinks, AIO water cooled systems, as well as custom water loops, the world is your oyster.


If this has inspired you to build your own PC, we would be delighted to help you.

If you want to build it yourself then we can help you with component selection and sourcing.

We will also be happy to build the system for you. Rest assured, we are very reasonable and your system would still be much cheaper than something bought off self.
