My old small form-factor desktop computer needs replacing, and I'm delighted to have found CaseEnd, which makes the case-hunting part much easier than it used to be in the bad old days of shared Google spreadsheets. It shows you pictures, prices, case volumes, how big a graphics card will fit in each—all at a glance. The downside: it has nearly convinced me that I can get what I want done in under 5 liters. I know, rationally, that this is thermodynamically impossible. There but for the benchmarks of God I go.
