Great quality

I ordered a custom keyboard with milky yellow pro switches and a few mods. I ordered it already assembled out of a lack of time and it came in really quickly.
When I got the chance, I opened it to take a few changes and was really pleased with the quality. It was gasket mount despite not having had to option to choose that on the website and it had case foam. A tape mod later the board sounds brilliant. The switches are well lubed… can only recomment and look forward to my next order 😊

Great case, got loads of potential

This case is great loads of potential, for fan placement, cable management, ease of part placement and overall visual look in any colour

Fantastic clacky switch

If you’re after something clacky look no further, these switches are also super poppy. I would spring swap them tho since the stock 57g spring is too light imo

Fantastic

Went for the red switches, absolute fantastic keyboard to use. Layout is quite small so possibly takes some getting used to but loving it.

Future proofing PSU

Happy with this PSU. Picked it because it had ATX 3.0 and PCIE 5 standards including the 12VHPWR connector without the need for any adaptors. There is an option for silent mode should you want it as well.

Sturdy Responsive and Quiet

I would love a set of keycaps with just the F Row - or to have the F row have light shine through and the multi-media options to be secondary (underneath).

The programs and games I use and play rely on the F Row a lot and its hard to see this F Row in a dim room - despite the RGB being at its brightest.

That's my only gripe. Everything else I love.

Great PCIE5 ATX 3.0 Power Supply!

It's expensive but it's one of the few 80 Plus Platinum PCIE5 ATX 3.0 power supplies available at the moment.

It's extremely well built, compact and quiet. I've been running it for a few weeks now and I'm extremely pleased how it handles power deliver to my 3080, I'd previously experienced issues where the graphics card could produce sudden power demand spikes which would cause system instability.

Since upgrading to the MEG Ai1300P I've had no such issues.

You get loads of cables, they are pretty good quality but could maybe do with integrated combs to make things neater.

All in all I'm impressed and would recommend!

Great future proofed and quiet Power Supply!

I needed a new PSU for my build and bought this as it didn't cost much more and had the new ATX 3.0 and PCIE 5.0 specs.

The 1000W power is way more than I need but the beauty of this his power unit is that I believe the silent fan mode kicks in at less than 50% load. In my use case this means it will always be silent under 500W until I upgrade to a more power hungry CPU/GPU.

Effectively I have a 100% silent build now. Passive CPU cooling, passive GPU cooling and a silent PSU. Case fans are off unless system is under super heavy load.

Has worked flawlessly since installed.
