Yesterday I was trying to fit the Small Z axis into a bounding box to determine what the footprint is most likely going to be, as well as comparing it with the currently recommended budget printers. Considering that the printer is likely going to be north of £649, I decided to go for better value; an analogy is that I'd rather have a slightly more expensive but filling meal than a slightly cheaper but not filling one.

Me in 2018's minimum and recommended requirements for an MSLA printer volume was at least 200mm in 2 of the 3 axes and ideally 300mm in X and/or Y, so I've increased the bed to 3 screen-areas (307.2mm) and the Z by 50mm to obtain around 230mm of Z height. This is a print volume that could fit a better percentage of my projects and files online (since they'd be designed for something like a 220mm bed in mind). The expected footprint is now expected to be 540x305x600mm.

I accedentally forgot the X axis linear rails and to make sure that the spreadsheet calculated the extra 2 roller rails, so the difference in price between the 204.8*163.6*170mm and 307.2*163.6*230mm is only expected to be a sub £10 difference: £6 for the longer bed and pennies for the longer leadscrews and linear rails.

As you can see from the top image, I've decided on a fixed-free leadscrew mounting arrangement. I put the values for the Suspense in an online calculator and it said that the critical speed was over 270mm/s, which I don't plan on exceeding. This arrangement allows for a smaller X footprint and smaller Z axis mount that doesn't have the roller rail cutout through it.
