More LGBT than RGB

Got this as it was the cheapest. Had read some reviews which pointed out the only negative was VRM's get a bit hot, within tolerance.

Came well boxed, and was quick to install. Is a real basic no frills board. The only issue I have with it is the RGB on the board always goes to rainbow, so is more LGBT than RGB.

Everything you need

Got this from recommendation for my build in store. Seems to be working great. It looks awesome, the lighting is irrelevant for me but if you've got a visible interior it's a nice feature. Plenty of features for me and pairs well with my fairly modest build.
The only thing that a first time builder like me struggled with was there appears to only be a lock-down bit at one end off the ram inputs but after a bit of force there's been no issue and ram seems secure.

Pleasantly relieved

Affordable, has everything you need and has extras to keep up with the more expensive brands.
Entry to midrange mobo that is compatible with a broad range of products.

Buying within a budget doesn't have to stress you, thinking you'll miss out on functions that the more expensive brands have on offer.

Great value but..

Comes with everything you'd expect for this price bracket with little effort required.
Pros:
Easy to install, good layout, everything needed in box for a standard build
Good quality components, SMD quality is great, VRM's haven't been of concern yet but I have yet to really thrash it.
IO cover and PCH heatsink lights are cool

Cons:
Asrock Software (like a lot of manufacturers) is poor, in this case the RGB software. It reverts to default, doesn't play nice with component sync (even bridging with Razer Chroma Studio), I now sit here, in the dark, waiting for a stable update.
