Secure enclosure for a single (tower) server - recommendations?

[pete]

I need a secure enclosure (floor-standing, ideally) for a single tower server (Dell T20) that'll stand up to the rigors of primary school life.

 

The schools don't have suitable areas to secure servers and I (and the auditors) would be happier with a steel box.

 

ideally sleek and form-fitting, but with sufficient space around for airflow / fitting the replacement server in X years time.

Security cages - this one encloses the whole thing, so removes the temptation to press any power buttons

Although why not use a normal cab and throw a shelf in? There are also acoustic cabs - great idea for when you need a PoE switch in an office or classroom.

I've considered adding to the existing wall-mount cabinets, but while it'd be neater it'll require a rackmount UPS, the doors replacing for mesh and I'd be adding ~35KG of weight to an already fairly-loaded cabinet (4 switches, CCTV box, phone system, NAS) that's located above a thoroughfare for small squishy people.

 

vs "Put steel box around to satisfy security/audit requirement".
