Hmmm... those old HDD racks don't match... and 2 new ones will cost £40.

Spray it silver.
New 40mm 2 pin fans on order along with a USB 2 PCI card.... I did find 40mm blue LED fans in the USA but the company couldn't process my credit card. Wouldn't let me PayPal it to them (even though they take PayPal) and send the fans to Ari. That was a first... a US company with a UK like "can't do" attitude.
