If it has to be cheap I'd take e.g. a Sun with 8x 2.5" SATA drives,
using 300 GByte WD VelociRaptors as a stripe over mirrors, or 15
krpm SAS drives.
Right now you can populate a SuperMicro chassis with 16x SATA 3.5"
achieving e.g. a 24 GByte dual-socket Nehalem with 32 TByte raw
storage (WD RE4; 4.8 TByte with WD VelociRaptor) for about
6.2 kEUR sans VAT.
