Well, this is how it started , a bookcase unit with 2 drawers from Argos:
After some adjustment and silent screaming, this is the result tonight:
The bookcase was £49.99 + £4.95 delivery
I used 4mm perspex cut to size from the local glass merchant £47.00 delivered
Door runners and handles and wedges from Lotus Nut £20 something incl p&p
Then there's all the electrics - the top drawer is no more, it's just a front with 2 magnetic catches to hold it in place, then inside it in the fixed in bottom drawer are 4 thermostats, 2 UV starters, 2 banks of 4 socket extension leads, 1 bank of 6, bet the village lights dimmed when I turned it all on!!!
There's still some tweaking to do, the decor needs adjusting, the temperatures need watching and thermostats adjusted accordingly....
But for my first ever attempt at a project like this - with my OH's help

- I'm well chuffed!!!!!
