1590b blend/bypass jack orientation

[Luke51411]

Dumb question, I'm wanting to build simple a parallel loop/bypass box with blend knob in a 1590b but I can't decide on how to orient the jacks so I was just looking for opinions and wondering what fallbacks/advantages of certain layouts I may not have thought of. The first though was portrait orientation with In and Send on the right side and out and return on the left. Or landscape orientation with all 4 jacks on 1 side. There is also landscape with In/out jacks on the short sides(seems impractical). Maybe others I haven't thought of. So what do you think? Also I searched for templates and didn't come across any but I know I've seen them before if anyone knows of any that would be great, not really necessary but helpful.
