An IDE to SATA converter (i.e. not via USB) shouldn't be too much of a bottle neck. The other option would be to pick up a SATA controller card that plugs into a PCI / PCIe slot on the motherboard, if you have a spare slot available.
If the motherboard doesn't support SATA it's likely quite old. Might be time to upgrade that too, perhaps? It'll probably mean upgrading CPU and memory while you're at it. Depends what demands you're placing on the machine, really.
Appreciate what your saying Kev and agree bud.
The media case was built up in 2006
Basically, i'm trying to build a media player with as little initial outlay as possible

Not a lot of funds and lots to spend it on so i'm scavenging various old pc's and software discs which are scattered around the house and trying to make good

Call it "gonads media player junkyard challenge"

As said on the other post with TB, I know it isn't going to blow anybody's socks off or break any records but if I can get it working reasonably well so that it does a job then i'll rebuild it properly when fund allow
