Backplates can be added to your graphics card to hide the, often ugly, circuitry that sits on top. If your PC is going to be on display, it is a really nice addition to your system.
The beauty of them is, you can add anything you want onto the plate. Got a Star Wars themed PC? Add Darth Vader on there. If you are a streamer or a business and have a logo, that can be added too. You also have the choice to add RGB elements, as above.
Price wise, you are looking between £50 and £100.
DRIVE COVERS:
Much like the GPU backplates, SSD and HDD covers add a bit of bling to your build. These are not always needed, as storage drives can be mounted out of sight, but if they are on view, maybe a cover is something to think about. Again, they are fully customisable to match any theme.
Prices are between £20 and £60.
GPU SUPPORT BRACKETS:
If you are considering extra customisations, chances are you are going to be installing a hefty graphics card. The problem with big graphics cards is they tend to sag and don't line up perfectly. This is because they are only supported by a couple of screws and the PCIe slot. A solution to this is a support bracket.
These can be plain, or fully customised. Prices range from £20 to £80, again, depending on the level of customisation and RGB.
CASE MODIFICATIONS:
This could be a whole page by itself. Case mods can range from adding cut outs for more fans to resprays and custom decals. For inspiration, head over to www.techpowerup.com
It's hard to put a price tag on this sort of thing as the level of work can be immense. If you wanted to go down this route, we would discuss your needs and provide an estimate.
GLASS PANEL ETCHING:
This is an amazing way to make your mark on a PC build. Glass etching is relatively cheap, but can have a dramatic effect, especially when paired with RGB backlighting.
