The crew will say that you can build it but I would disagree. Do you own a soldering iron and are you comfortable using it? Even many of the guys who would say yes, spend lot's on time on the Bottlehead forums trying to figure out what they did wrong. In fairness, it seems that most of the time they are able to get it resolved.
For me, I knew that I wanted speedball upgrade and custom caps and pot right out of the gate. I decided to get someone to build for me and I'm glad that I did.
Is the Crack a build that I could tackle on my own if I have next to zero DIY experience, or would it be better to have somebody build it for me? I'm starting to get tempted by the nearly universal praise and the reasonable price of the amp.

I've soldered in the past and own a soldering iron, but I can't say I trust my electronics knowledge enough to tackle it, at least not on my own. I might just make it a weekend project with a friend who's more experienced building electronics.

I would expand on that and continue to say: do you also own a multimeter and understand the underlying electronics associated with the build?
I guess I am competent enough to solder - after a few run-ins with SMD soldering - but I know little on how to test with a multimeter, and how it can be used to identify parts of poor soldering.
Regardless, I myself will still jump into doing the crack, primarily so that I would understand which part to take off if I were to do any modifications in the future.
just curious: how does one learn to do SMD soldering before general multimeter use? SMD solder and reflow is pretty advanced for even a hobbyist
When all the stuff has been put in a kit, the skills for SMD soldering can be considered isolated from learning multimeter use. Putting things in the right place and applying standard methods to fix each part, doesn't need the ability to read measurements. Multimeters then become a "turn this device to this mode and check with a unsoldered plug" step, when a well documented build instruction is included. The need to use the multimeter is further reduced if the parts come in labelled bags which are referenced with the documents.
In this case, I am one of those people. Funnily enough, I made a few cables and adapters well before I obtained a multimeter. I know roughly what each mode does, but it's useless if I don't know where/how to check components, and what measurements I should be expecting. At best I can check if a solder joint is solid by checking continuity, which only made soldering audio connectors easier to debug.
I also learnt SMD skills though youtube videos, and playing around with the internals of a deceased computer mouse.
SMD soldering isn't bad until you get to chips and stuff that use the solder balls underneath... Or have 100 plus pins on a chip that is the size of a keyboard key. At that point, you need a different approach. I find it just takes patience, and a very good soldering iron / tip. I'm a fan of the Weller WESD51. Really good tweezers are also required.
For the most part, learning SMD soldering is straight forward. Just get protoboard and practice soldering SMD parts to the underside of it with all the traces. I find that I would silver up the pad on both sides then heat up the solder as I lower the part into the molten solder. Remove heat, allow it to harden. I guess I try to avoid as much contact with the part as possible and only try to touch the PCB.
Ah, that makes sense! I went to school for EE and the first thing we did in the lab was learn to use the bench multimeter, power supply, and oscilloscope. Then we did breadboard prototyping, then learn through hole soldering, then SMD hand solder and also reflow. That might have even been my second year where we actually did any soldering if I remember correctly, which is why I was a little surprised.
SMD by hand is bad. Only a few packages are fairly easily doable by hand, like the bigger SOT and DPAK form factors. But using solder paste and a reflow oven, it's cake. Even better if you have a pick and place machine to do all the heavy lifting.
I have a JBC soldering station. It's the best I've ever used and will probably own it for the rest of my life. Heats to melting temp in 2 seconds flat from being cold to the touch. Also has the fastest compensation curves I've seen, besting that of weller, hakko, etc. All that goodness comes at a price though, but worth it for EE's and extreme hobbyists.
