Just an observation on my side. Will you be leaving the xtal leads that long? Critical frequency generating parts like that should have leads as short as possible right?
Maybe it is just the way the pic looks.
While I can't speak for the OP's original intentions with this particular set up (aand, I know what I would do, but TIMTOWTDI) I can speak to building practices and general rules.
There are several considerations to consider when building a rig:
1. Mechanical issues
2. Frequency stability
3. Design Flexibility.
One reason to keep the leads as short as possible is because a component lead is significantly weaker than a circuit trace on a pc board. Stress on a component lead can also weaken or break the connection between the lead and the material inside the component. Milsurp Carbon composition resistors (IE, what you find in Heathkit radios, and others of that era) were prone to breaking internally if you stressed the leads according to my Elmers. While this is still a concern, construction practices can eliminate much of the worry you may have of overstressing the component.
Frequency stability is affected by component length because the materials used to make the component ain't perfect. Component leads can contain iron, copper, tin, lead, silver, and other metals based on the use, era in which it was made, and laws governing its making. These materials will introduce stray capacitances/inductances/resistances into the circuit that will affect the frequency of the oscillator and the oscillators ability to oscillate. These effects are more pronounced at higher frequencies. 10MHz is right at about the point where things get tricky. The main problem you will have with keep long component leads is stray inductance. This will deresonate the circuit, and it won't oscillate. I'd say it's no worries in this situation, and the OP is good to go.
as far as design flexibility, choosing different crystals is one way, but I would investigate other ways, like building a "Rockless" (see QST, Nov 2009)
Just a personal choice.
