I need to purchase a metal electric enclosure / cabinet to mount a VFD and associated gear at the rear of a milling machine. Something about 300 x 300 x 200 would be ample and I see various options available on eBay, including cheaper boxes under £30. Has anyone had any good experience with these or are they cheap and nasty (very thin sheet metal, poorly fitting doors, etc.) compared with branded units? I emailed one eBay seller to ask about the thickness of the sheet metal and received no reply.
