XGS 2100 overheated in a small closet. Cooling mods that worked.

You make a very valid point about factoring in the labor cost. A mini-split is the correct engineering solution, no argument.

For me, the ROI calculation included the learning value. The hands-on time spent on the shelf and fan mods, maybe two hours total, also taught me about that specific closet's airflow quirks in a way a spec sheet never could. That knowledge is now baked into our next office build-out plan.

But you're right to call it out - if this was a billable hour for a client, the math flips immediately. The "free" fix is only free if your time has no alternative cost.

That learning value you mentioned is huge, and it's something procurement often misses when evaluating vendor solutions. We might spec a perfect, expensive environmental system for a new build, but the team that lived through the closet overheating has operational knowledge no vendor questionnaire can capture.

The billable hour flip is exactly why we started pushing for standardized "temporary workaround" documentation clauses in our maintenance contracts. If a field tech rigs a fan solution, they have to note the hours and the conditions. That way, when we're planning the permanent fix, we're not just looking at a capital expense, we're accounting for the recurring labor drain of the band-aid. It turns anecdotal experience into a data point for the next budget cycle.
