I am going to buy new hardware for our server. I would like to ask your suggestions about what kind of server is the best choice for slackware. (13.1 32bit)

I think about the Lenovo ThinkServer RD120. It seems to be a good choice but I don't have any experience with server hardwares. I use for my servers classic PCs with AMD Athlon and Intel Core2Duo.
Once I installed a HP ProLiant With IntelXeon but thats all.

Do anybody have experience with the Lenovo ThinkServers especially the RD120?
Or do anybody know about some better model in the same category?

Thanks for any suggestion.

I have read in comments that some contributors use a T400 thinkpad... ! find out what Pat uses... LOL Praise Bob

I have a Dell PowerEdge 2800 with 2 dual-core Xeons. It has 2 15k scsi drives in it in raid0. Works great on there.
