I came across this to house the Darkly Labs Emblaser laser machine...Might be worth checking out costs?.....its unusual but seems to be very effective......https://darklylabs.zendesk.com/hc/en-us/community/posts/208849688-The-Emblaser-IKEA-Enclosure-
I worked out the cost of two glass fronted drawers mentioned (£60 UK) ex IKEA
Shelf 100cm x 58cm £8 (UK) ex IKEA
Other items such as the struts..switches, seals, fan etc may be sourced at cheap places.
Saves a lot of work doing it this way!!
A closer look at the drawer I noticed that the glass may be replaced by the appropriate colour and thickness by acrylic.
(However, prospective purchasers should check if the glass IS removeable)!
