Well the look I was thinking of is to not use right angle fittings if possible and just use compression fittings so everything all the same.You can just bend the tube to fit and use compression fittings, but it depends on how complex you want things to be and what look you are going for.
Well I think there should be at least 100mm maybe more clearance so I should be able to just bend the tube and use a compression fitting.Largely dependant on where the straight after the bend sits distance wise from the component. If the straight section is close to the component then you'll probably need to use a 90deg fitting. If it's a wee bit away then you'll be able to bend the tube. You probably need a good inch for a bent tube from cut to downstream of the bend - straight.
Also I think it looks better not having big right angle fittings everywhere.If you've got the room to get your lines straight, go for it. Cheaper to bend a tube than add a load of fittings...
