Thank you, its now 17 years old but still relevant given everything still fits.
A few mods were needed, firstly a window stealth mod and rewiring to usb 3 spec but I am pleased with the result.
I have been looking around for cases to replace these but everything seems to look a bit "Steel" and flimsy these days with little to no provision for 5.25 bays which are still very useful.
I was a little concerned about cooling but after finding these Anidees 80mm ARGB fans thats really not an issue with lots of air in and out and maintaning a whisper quiet operation.
