this is a Compaq ML350 G1 w/SCSI backplane. if you bought coffee at a popular coffee restaurant in the early 2000s, your transaction may have gone through this computer (disks were wiped when i purchased it)

also, a life pro-tip: recycle your old computers while you're still able to lift them 🤣

update: i took the bathroom scale downstairs and these two pieces of equipment total over 116lbs. probably more valuable as scrap metal than electronics recycling
