Equipment Light box / light tent

Hi guys, I'm wondering if I can get some advice on a light box/ light tent, for taking photos of computers and other products.

Ideally less than £50 if that's possible?

 

hi what about this

That's what I need but I think it needs to be bigger to fit a mid tower in .

 

That's the exact kit we bought, stitched wrong so it wouldn't fold properly and left the lights on for in excess of ten minutes and they started to melt. Got a full refund.

Big enough for a mini itx case, maybe an Marx case.
