I expect there will always be custom-built cluster systems that target proprietary software applications or specialized environments. Those systems are built by experts for experts and just about every design decision is painstakingly made. HPC clusters for the masses will not be able to go down that path.
Volume HPC cluster solutions need to move away from cafeteria selection of components to pre-defined, flexible designs that meet a broad spectrum of user needs. This will take a lot of complexity out of purchasing HPC clusters and remove the need for the customer to be a cluster systems expert. I'm not suggesting that cluster purchasers have zero understanding of the system, but it needs to be simplified to understanding the application workload needs that will run on the system.
Purchase time decisions for volume cluster solutions need to center on aspects that affect execution in terms of performance but do not risk introduction of component integration issues. That means that components like operating system, cluster provisioning, interconnect hardware, and resource management software need to be set and unchangeable at purchase time.
Allowing total piecemeal selection of components at purchase time requires the buyer to know how everything fits together, have the tools and knowledge to build the system, and/or pay for the services to put it together. This approach works for veteran buyers who easily justify the return on investment but is much harder for the (new) volume cluster buyer.
Volume cluster solutions are more like partnerships of many components with the solutions provider as the focal point. Solidify the solution component partnership, and the solutions themselves become easier to produce and ultimately become more stable product. That helps lower barriers to using HPC clusters.
There's a key set of partners I haven't covered yet, though, the application vendors themselves, but that's another topic all together.
