Thanks for the replies y’all, much appreciated. lol I’ve had a feeling that 84hp would not be nearly enough. Definitely switching to a case I can “grow into”.

Generally, the rule of thumb on first cabs is that you should set up for a MUCH BIGGER build than you think you'll need...because when you're starting out, it's actually more likely to be too small. So if you thought that 1 x 84 was enough, the 2 x 104 of a Mantis is probably what you should be using. Then, if you think the resulting build is just too much, you can more easily pare the module complement BACK. And this tends to be an easier task than ripping it all down to do different subsequent 1 x 84 builds to get things right.
