Computer Requirements
Acquisition
Make sure to get a computer with sufficient PCI/PCIe slots for the camera framegrabber cards (usually 2 cameras/cards for dual-view) plus whatever other peripherals you need.
Otherwise the main requirement having sufficiently fast disk write speed to handle the camera data. Depending on the use case, solid state drives (SSDs) and/or RAID0 with SSDs may or may not be required. Individual users should consider their requirements.
The sCMOS cameras used with diSPIM can generate 800 MB/sec (100 fps at 4 MP, 16 bits per pixel). However the maximum possible frame rate of the camera is never achieved for diSPIM.1) Typical maximum acquisition speeds are 1024×1024 at 50fps or 512×512 at 200 fps; both these situations both generate 100MB/sec. The average data rate, and hence hard drive speed requirement, is usually even less because most commonly acquisition occurs in bursts (i.e. there is time between successive time points).2) At present only one camera works at a time, though there is a scenario in which both cameras could be used simultaneously and thus double the data rate.
100MB/sec is doable for a typical magnetic hard drive, and it is easy for a single SSD. If the data rate is too high for a single SSD, use SSDs in RAID0 configuration (e.g. 4 SSDs in RAID0 can achieve >1 GB/s).
To benchmark your PC's hard drive write speed you can use Crystal Disk Mark. I'm pretty sure the relevant score to the Micro-Manager plugin use case is the “Seq” “Write” score (Sequential (Block Size=1MiB) Read/Write with single Thread).
Data Analysis
Having lots of RAM speeds the analysis; ideally the entire dataset can be held in active memory. Ideally get a computer with CUDA-capable graphics card because some of the data analysis software can take advantage of it to speed the computation (OpenCL is a competing framework for GPU computation). This is a nascent area and depends on software support; many software developments data analysis are forthcoming so it's hard to say exactly what will be the best hardware in the long run.
Specific suggestions
ASI has successfully used Dell Precision T3600 with 8-core Xeon CPU, 4x SSDs in RAID0, 64 GB RAM, Nvidia Quadro K4200, and enough PCIe slots (2 camera framegrabber cards, graphics card, and RAID controller).
